Keyboard spams multiple letters at once (CoolerMaster CK352)

I have this fancy CoolerMaster CK352 keyboard which is very comfortable writing on. However for quite some time now I have this issue that when I hit a letter, lets say "o" I don't get "o" but "ooo". So it spams multiple letters with one single hit. First thing I did was resetting the keyboard and picking out the keys and gave it a good clean with Isopropanol which didn't change anything. This issue also happens only with certain letters and not with all of them. I also  added a line in my 00-keyboard.conf where I specified a delay when a letter should be repeated when the key is kept pressed. This didn't help either. Any idea at what I could try?

Thanks in advance...

sudo evtest

hit the bogus key *once*, then ctrl+c and check/post the output.
If there're 3 events that all have MSC_SCAN, its's most likely coming from the hardware. Maybe the switch is bouncing.

This issue also happens only with certain letters and not with all of them.

Is there a pattern to this?
