I umm, seem to be having an issue with the latest version of dwarf therapist.
Some of the unit names don't match, which means something funny is going on.
I have two citizens who ingame are called one thing, but are called something else by dwarf therapist.
One of them is a Pilgrim, the other is a Monster Slayer. So, I'm wondering if they are using this new assumed identity thing, and dwarf therapist isn't picking that up.
If the new assumed identity thing is different from vampires' fake identity, I am quite sure Dwarf Therapist does not pick it up.
If there is something weird with your save, it would be easier for me to debug if you uploaded it.
Also Monster Slayer are currently considered like mercenaries in DT: assignable to squad and not hidden when you don't display visitors (but the names I checked were correct in my fortress).
Okay, here's my save game:

There are two citizens, and having used legendsviewer to look, Dwarf Therapist is reporting them under their real names.
Rel Anoeslik, "Rel Loverblocks", Pilgrim, is actually Vemini Matchedmurk.
Nique Gujegwuspin, "Nique Tunnelcradled", Monster Slayer, is actually Rafovi Wisdomhexes.
Oddly, they're both married, and looking at their spouses, shows their real name there as well, but the spouse's relationship screen shows the false name.
Confusing !
