OH I just reviewed this again and think the change is correct (thought the github diff makes it very hard to understand)
What is happening is that you have a non staff group owner and need to allow the public group edit tab to work. It was sharing locale stuff with the staff locale file so it clearly fails.
@tgxworld can you review this and perhaps clean it up.
What we want to make sure is that we don’t have duplicate strings in admin/non-admin and duplicate templates here.
