Crouch/Jump keybind bug

I usually play with flipped crouch and jump keys (Jump = C, Crouch = Space) 

I've discovered that using these binds in the beta causes the player to both jump and crouch when just inputing jump. This causes the player to always land in a crouched position.

I think there is a hidden bind that forces c to be crouch, because if i bind jump to another key it works normally. This is pretty frustrating as I use these binds in every game.

I know its probably a low priorty but would really appreciate a fix for this.
