I had to reinstall my Mac because of the iOS14 issue. Since then, all Buttons (LEDs) are dark on my Traktor Kontrol S4, except the one I am pressing / which is active, like the Play button, while a track is playing from this deck. Everything is working fine, but I can't see anything in a club, if it is like this. Looks like a kind of dark mode. Please help! Thx!
