They are not bound to something else, they are bound correctly in game. I've hit reset defaults to make sure of this.
However it's not even registering the combo of the buttons, if I hit Alt+1 or 2 nothing happens, i've tried to rebind them to even another action. It does not register the two of them together. you can hold down alt, and it will show "Alt + ...." It will register the ALT key, but not Alt+1. This is a suddan problem, it was working fine a couple days ago
