Deleted a default navigation item

[sixlxvi]

I deleted the built in members navigation item and some of its children. Apparently, I had it set as a child of a custom nav item, which I deleted, so the children were deleted too.

I remade one using members as the ID but it XF doesn't pick it up as a default so its automatic phrases/conditions/relationships don't behave the same. Is it possible to fix that?
