Strange problem with some keys on Analog Keys

Keys silent

So, I’ve recently bought myself a second hand AK. But I seem to have an issue with a couple of the keys turning silent once in a while (I think specially after I change/adjust sounds, but not always). It’s the 8 or so keys to the very left of the board. There is no Multi Map, or other button pushed (as far as I can see) that could cause this. I can solve it by pressing on some of the keys a couple of times. Anybody know what the issue could be? Is there some kind of functionality that does this…

that?
