Yes, the earlier / oldest ones in the listing have privacy issues on one or both profiles, so the PM or Admin must do the merges. Some members of the Arborist group have been trying to reach the PM or Admin to complete the merges.
Remember that just because a merge has been proposed and may have gone past the default time or even if PMs have approve a merge, the profiles should still be reviewed to determine if a merge should be done. If there are parent discrepancies, those need to be straightened out first, merging those profile should be done before the children are done, as an example.
