I has just imported my photo library into Lightroom Classic and would like to tag the people I know. I used to do some commercial photography (weddings, etc.) so there are a number of folders for which I won't know who the people are. After the import (and face recognition) had completed, I selected all photos in a particular folder, used the "Remove Face Region" option, let that complete and the photos in that folder showed as "No people found". This was repeated for several other photos I wanted to exclude.
However in the "People" view with "All Photographs" selected, some of these photos are still being shown in the "Unnamed People" list. Opening any of these photos shows the box around the face with the "?" callout. This doesn't appear to be the case for all of the photos I've removed the face region from.
Any ideas why some of these people are still requesting a name? Thanks.
