I think I have found where the problem is located. It looks like it might be a conflict between BB, your multisite plugin, default tabs, and tab creator pro.

I have done some further looking into this and have deleted the plugin as it is messing with my sites.

When plugin inactive, groups show up properly in their subsite.

When plugin activated, it corrupts Groups and subsite Activity Feed.

Corrupts groups:
1. It duplicates the groups that are part of the subsite in the mainsite and hides them from the subsite (breaks the subsite’s Group page).
2. If I deactivate plugin, repair the community (using the buddyboss repair function), the groups reappear in the subsite, but they also are remain duplicated in the mainsite.

Breaks the subsite newsfeed
3. Newsfeed is no longer visible in subsite. Even after deactivating and deleting plugin, trying to repair community as above, this is still broken.
