Having trouble with Facial recognition

[Calistogagrower]

I have several hundred people recognized by name in my catalog. One of those people disappeared while I was adding additional images to the person's file.  How can I have the system search for this one person again without having to do a full reset and lose all of the hundreds of other people already recognized by name?

What OS and version of Elements are you using?

Can you give us a little more detail about what happened. 

What do you mean when you say a person "disappeared"? 

Are you talking about the Named or the UnNamed People tab? 

How were you "adding additional images to the person's file?"
