The JOptionPane dialog window appears when pressing the wrong button on the GUI

I am working on a racing Simulater Software. I have already made the GUI for assigning custom buttons to the keystrokes of the hardware. I made a dialog window appear when one is pressing the button "red1". The first attempt at compiling after restart is normal. The second time and every time afterwards the button stays pressed and the dialog appears no matter what button I press. This is not intended by me.

It might be good to know that my ultimate goal is to synchronise the Software with the Hardware (when it comes to pressing buttons) and to assign custom buttons to the keystrokes of the hardware via the software.
