script acting crazy

For some reason that I don’t know my controller has started to act like crazy.

For example, as soon as I select a track in Ableton, the leds on my controller changes their colour.

I have multiple on/off buttons and on = green; off=red. but when I press a button to turn off… the led fedback is yellow or even off but as soon as I press another button the previous button receives the right colour

really weird, it drives me crazy.
