So MobileSheets matches on name, and if the names don't match, it will delete the old group and create a new group.

Thanks for the reply!

Actually, what happened is that nothing was deleted. Neither side thinks the other side, with a different-named setlist, is the "same" setlist as the one it has. So it keeps the one it has, and pulls the other as a new one. So instead of syncing a single setlist between devices, both devices end up with 2 setlists: the one with the old name and another with the new name.
