Button mapping

[Chaf]

Hi. I'm playing on arcade stick and I've noticed that my buttons are already set on controls I didn't wanted or set in the options. Like RB set on Hold and RT set on Rotate Right. Since I already got a Hold and Rotate Right button, this makes me mess my moves, which is unfortunate.
Is there a way to totally unbind buttons I never asked? Like putting nothing on a button I didn't set in the options.

As always, thanks for running TOP.
