why I cannot render the first layer After I rendered an animation in second layer, my render always render the second layer. I changed my camera setting and clicked 1st layer and then click render, but it still pops out the rendering of my second layer (my animation render). 

How can I change back to render my first layer again? There are some pictures about my interfaces below, if they help. 




Link to .blend file:
You need to go in the Properties panel > Render > Post Processing, and deactivate Sequencer. I quote the Blender manual: "Sequencer
Renders the output of the Video Sequence editor, instead of the view from the 3D scene’s active camera."
