The "ghost" profile is a commonly occurring problem at WikiTree, Chris. A merged-away profile hangs in the system as its own sibling.
I don't know if the problem clears on its own after some time, but it can be fixed by detaching the "ghost" profile from its parents, spouse, and children.
Fixing the problem on the parent's profiles is simple enough, since there are only 2 parents involved. But if several children and/or multiple spouses are attached, fixing all the attachments could take a good bit of time.
I'll work on the Dollas/Dallas family issue, but someone else may have to work on the Grutzmacher problems. Those may require some expertise in non-English alphabets.
