Armor Abilities not working

Hi, not sure if anyone else is having the same problem - using wired controller on MCC PC, Halo Reach. Armor abilities won’t work. No matter which button layout I use or change it to. At first I thought it was RB, but once I changed to bumper jumper, it worked fine. It’s literally just armor abilities, no matter what button i’m using, don’t activate. Campaign, firefight or multiplayer, doesn’t work.

At first, I had to hold down both left stick (click it in) and use armor ability button to activate (weird, I know), now nothing does anything at all.

Any suggestions? is it a driver problem?
