Armature layers is the thing that was before bone collections (prior to ~4.0). Judging by the code (i am not the dev of the addon) this function is only for switching to collider bone. This one is not functionally most important imo, because colliders works fine without using it.

It is possible to fix it for bone collections, but I need to dig up into old references, because I don't remember how armature layers worked.
