Group navigation menu ordering issue

I’m using BP 1.7.2 and BP Group Extras 3.5.7.

When I go to Extras–>and reorder the items – Home, Activity, Forum, Admin, Members – and hit Save, it works great.

However, I have BuddyPress Docs and BuddyPress Invite Anyone plugins installed which extend the groups. By default they create navigation links in groups titled “Docs” and “Send Invites”. If I try to change the order of these and hit save, the changes don’t hold.

Here’s what I want:

When I hit Save Changes, it returns to this:

Notice it just returns Docs and Send Invites to the bottom every time.
