Xbox Series S controller binding problem (I think)

I’m just starting off in career mode. Spent over an hour mapping my control scheme on a standard Xbox controller. I’m having 2 specific problems right now (although there are probably more, but I got frustrated and quit). I’m in the Cessna 172, I’ve mapped my parking brake toggle to RB + X, throttle increase to A, and throttle decrease to B. When I try to release the parking brake with RB +X, it instantly re-engages. When I try to increase throttle with A, it instantly snaps back to 0% when I release the button. Don’t know if there is some hidden setting that I need to change somewhere. But, as of now, I obviously can’t go anywhere.

This may or may not be of some help for bindings etc.
