Range Attack & /Doability 1-6 bug

[The Basura]

I have issue with throwing range weapons, i have Throwing Knifes equipped both in Range and Ammo slots and currently set up as #8 on my Button Set#1, Doesn't work i tried different distance, and different ranged items, I also seem to have a problem with setting up a hotkey for my Feign Death hotkey, a basic /attack off /doability 4, doesn't trigger anything. Unsure what to do.
