Controller remapping in campaign

So I am encountering a bug with remapping equipment and grenades in campaign. My goal is to have equipment on up-dpad with grapple: up, wall: down, dash: left, and sensor: right. When I remap grapple to up-dpad, it overwrites equip plasma grenade in the grenades category. When I remap plasma grenades to up-dpad, it overwrites equip grapple (slot 1). This cycle never ends and I can not reach my remapped controls I desire. Just interested in reporting it and hoping it gets fixed (or someone can help me).
Thanks!
