Good news is the PM of that profile is active, so maybe they can help getting them identified. That PM has had messages left on profile, private messages sent, but doesn't seem to change the profile names, unfortunately. There are almost 30 profiles in their watchlist with that Suggestion on them and many had already had a comment of some sort added to the Suggestion, indicating that they were contacted. Part of the problem can also be, have sources been found for one or the other version of the name.
The PM may not understand that one name should be in the LNAB and other variations can be in the Current Last Name or Other Last Names field.
