I have three scenes in my program.
When I start it I see the first scene with all the buttons.
Then, when I go to the second scene I only see the the label, the buttons are not showing up.
On the third scene everything is working fine, I see the label and the buttons.

So the question is, why are my buttons not showing up on my second scene?

I tried to switch the order of setting up the buttons and scenes, so that scene 2 (volume) is the third scene and the third scene (resolution) is the second scene.
Everytime the second scene not showing the buttons.

```java
package view.options;

import javafx.application.*;
import javafx.scene.*;
import javafx.scene.control.*;
import javafx.scene.control.Label;
import javafx.scene.control.Slider;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class Options extends Application {
    Scene optionsMenu, volumeMenu, resolutionMenu;

    // Create the labels
    Label optionslabel= new Label("This is the options scene");
    Label volumelabel= new Label("This is the volume scene");
    Label resolutionlabel= new Label("This is the resolution scene");
    Label labl_message = new Label("Volume settings");
    Label labl_generalvolume = new Label("General volume");
    Label labl_effectvolume = new Label("Effect volume");
    Label labl_musicvolume = new Label("Music volume");

    // Create the buttons
    Button optionsButton= new Button("Go to options");
    Button volumeButton= new Button("Go to volume settings");
    Button resolutionButton= new Button("Go to resolution settings");
    Button saveButton = new Button("save");
    Button exitButton = new Button("exit");

    // Create the sliders
    Slider slider_generalvolume;
    Slider slider_effectvolume;
    Slider slider_musicvolume;

    @Override
    public void start(Stage optionsStage) {
        // Setup the sliders
        slider_generalvolume = new Slider();
        slider_generalvolume.setMin(0);
        slider_generalvolume.setMax(100);
        slider_generalvolume.setValue(50);
        slider_generalvolume.setShowTickLabels(true);
        slider_generalvolume.setShowTickMarks(true);
        slider_generalvolume.setBlockIncrement(10);

        slider_effectvolume = new Slider();
        slider_effectvolume.setMin(0);
        slider_effectvolume.setMax(100);
        slider_effectvolume.setValue(50);
        slider_effectvolume.setShowTickLabels(true);
        slider_effectvolume.setShowTickMarks(true);
        slider_effectvolume.setBlockIncrement(10);

        slider_musicvolume = new Slider();
        slider_musicvolume.setMin(0);
        slider_musicvolume.setMax(100);
        slider_musicvolume.setValue(50);
        slider_musicvolume.setShowTickLabels(true);
        slider_musicvolume.setShowTickMarks(true);
        slider_musicvolume.setBlockIncrement(10);

        // Setup the main button
        optionsButton.setOnAction(e -> optionsStage.setScene(optionsMenu));
        volumeButton.setOnAction(e -> optionsStage.setScene(volumeMenu));
        resolutionButton.setOnAction(e -> optionsStage.setScene(resolutionMenu));
        exitButton.setOnAction(e -> Platform.exit());
        saveButton.setOnAction(e -> Platform.exit());

        // Setup the layout and add elements to it
        VBox optionsLayout = new VBox(20);
        optionsLayout.getChildren().addAll(optionslabel, volumeButton, resolutionButton, exitButton);
        optionsLayout.setStyle("-fx-padding: 10;" +
                "-fx-border-style: solid inside;" +
                "-fx-border-width: 2;" +
                "-fx-border-insets: 5;" +
                "-fx-border-radius: 5;" +
                "-fx-border-color: blue;");
        optionsMenu = new Scene(optionsLayout, 300, 250);

        VBox volumeLayout = new VBox(20);
        volumeLayout.getChildren().addAll(volumelabel, saveButton, optionsButton);
        volumeLayout.setStyle("-fx-padding: 10;" +
                "-fx-border-style: solid inside;" +
                "-fx-border-width: 2;" +
                "-fx-border-insets: 5;" +
                "-fx-border-radius: 5;" +
                "-fx-border-color: blue;");
        volumeMenu = new Scene(volumeLayout, 300, 250);

        VBox resolutionLayout = new VBox(20);
        resolutionLayout.getChildren().addAll(resolutionlabel, saveButton, optionsButton);
        resolutionLayout.setStyle("-fx-padding: 10;" +
                "-fx-border-style: solid inside;" +
                "-fx-border-width: 2;" +
                "-fx-border-insets: 5;" +
                "-fx-border-radius: 5;" +
                "-fx-border-color: blue;");
        resolutionMenu = new Scene(resolutionLayout, 300, 250);

        // Setup stage and start it
        optionsStage.setTitle("Options");
        optionsStage.setScene(optionsMenu);
        optionsStage.show();
    }

    public static void main(String[] args) {
        launch(args);
        System.out.println("exited successfully!");
    }
}

```

So, where is the damn bug?
I don't get it.
Is it some kind of Java or JavaFX voodoo that you can't see the buttons of the second scene?
