I have my keyboard set up. When I load VIA to view the key tester, some keys aren't working correctly and some aren't working at all. The issue I am having is that some keys press both keys. Like pressing "s" presses both "s" and "a"
Does anyone know what could cause this? I can't see any joints being joined and I don't know what else to look for
