Driving RGB LED with Constant Current Driver - Only Blue Working
Let's tidy up.


Rotate 90° anti-clockwise.
Rotate 90° anti-clockwise.
Show your power supply ground connection. You can use GND symbols for everything connected to GND and eliminate some wiring to tidy up your schematic.
Show your power supply + connection.
Untangle the wires here. Can you see anything odd with the wiring of the three LEDs? (I can.)
Sort out this neatly.

Try and make your schematics read neatly from left to right. Positive voltages go to the top and negative or ground to the bottom of the drawing. That's why, when you rotate the board schematics so that the text is the right way up you'll find the GNDs at the bottom and V+ at the top. The LEDs are the right way up.
Tidy up the wiring and add the new diagram to your post to show your progress.
When you do this the reason for your problem should become apparent.
