iPhone photos misidentified a person, then removed that it WAS a person

I discovered many photos of good friend "Susie" had been misidentified by iphone as another friend "Katie". In each photo, I selected, "this is not Katie". When I tried to correctly identify Susie, the little face with the question mark was gone (on all photos with same action) so it 1) it appears that by removing the incorrect identification, it removes the possibility that it is anyone else, 2) there appears to be no way to correctly identify Susie in these photos. It's like there is not a person to identify at all. There are many photos correctly identifying Susie, so I am confused as to how it even happened (one is blonde and one is brunette).

Anyway, is there a way to turn faces back on or some other technique to reflect even an unidentified face?

Additional info: I am on a iphone 13 Pro, on ios version 18.3.1
