Controller remap question

Hello all. I just picked up LE and I am REALLY enjoying it a lot! I cant believe I slept on this game for so long!

I am having a tough time trying to reassign the buttons on my XB controller. It seems you can’t rebind the “A” button at all?

My controller is XB Elite2, in working order.

When I click reset then wait for it to ask for the input nothing happens for “A,” its staying at the default layout.

Certainly playable, I would just prefer my own desired layout. Appreciate any response in advance, thanks!
