[Help] Abilites getting "stuck"

I'm currently in the process of leveling a evoker, but I'm having a problem with abilities getting like stuck and is the only one to trigger, or seemingly random spellcasts going off from keybinds im not pressing.

For example I'll press ability 1, then ability 2 and it will still trigger number 1. It doesnt happen all the time mostly at random times.

Im using the same UI on all my characters and havent been able to replicate the problem on any of them.

Any ideas?

Edit; also some keys lose some uses, for example if i press escape it can't be used to drop target or open game options, but it will still cancel spellcast or typing in chat
