[2023] [XBOX] Can't use the 'A' button to attack llamas in the shop or assign ammo to defenders in game...

As the title. This started last week at some point. The llama thing not a big deal as I can use right trigger to hit the llama, but I'm stuck using melee defenders as hitting A won't trigger the assigning of ammo to a shootey defender. I don't see anything in setting for this. Checking if this is others' problem as well. The button otherwise works (I can jump).
