Right Click Doesn't Work on Client

I was checking out the club system and created one to test and delete. I couldn't figure out how, so I searched it up. You're supposed to right click it and hit delete, apparently. I tried this, but right clicking does nothing for me. I also can't delete friends or promote club members. I've always been able to get around this (blocking friends to delete them) but now I have no solution and can't deal with a random club every time I launch. Can somebody help? (Right clicking works fine in-game.) I use Linux by the way, so yea...
