Arrow Keys Behaving Strangely / Stubbornly

I’m having a bit of trouble using the arrow keys for anything other than navigating up down left and right. No matter what I assign to those 4 keys, it usually defaults to the navigate functions. Sometimes it does allow me to change their function but it usually falls back to navigate, even though it says differently in the key command menu.

Is anyone else experiencing anything like this?

Same here
