Librem 13v1 caps lock not working, and some key combos

On my librem 13v1 caps lock stopped working. And also the following key combinations don’t do anything and the don’t even return any keyevent in xev:
left shift + z
right shift + q
left ctrl + tab

Using parabola(arch), but it is the same in ubuntu live
Using coreboot, but happens also with factory bios
