Options for tagging PEOPLE photos are incorrect since upgrading from High Sierra to Catalina

. However, NO FIRST-LAST NAME TILE WAS CREATED

You may have created a second People album for your daughter, that is still hidden.

When you view a photo with her face, and there is a thumbnail with her face in the Info or below the enlarged photo in the Details section,

• click the tiny thumbnail to open the People album for this face.
• When the People album opens, scroll down to the commands at the bottom of the album. If the album is still hidden, you should see a command "Add to People Album" at the bottom of the album. Click this. The album should appear at the bottom of the People album and you can drag it onto the main album of your daughter to merge it into her main album.

Photos 5.0 on Catalina is treating the faces slightly different from the previous versions. It does not allow us to assign the same person name to two different faces in the same photo. If Photos should have incorrectly labelled a different face as your daughter, you will not be able to assign her name to the correct face, unless you remove her name from the wrong face.

While Photos is still updating the faces database, I would enable the the option "View > Show Face names", if you have not already done so, so you can see exactly, if the names have been assigned to the correct faces.

Please be aware that when naming people in photos, if the name suggestion comes from an entry in your Contacts application, then the name under the face in Photos will only show the first name of the person, not the person's full name. Apple provides no configuration settings for controlling this behaviour, which can lead to very confusing situations where everyone with the same first name, but different last names, will show up with the same name in Photos. I have no idea what Apple was thinking.

Please Apple, listen to your customers and do not make Photos so simple that it actually becomes confusing and difficult to manage!

There is only one way that I have discovered to show the full name of a Person in Photos that has been tagged from a Contacts entry:

1. Display the People tab/area in Photos for macOS.
2. singe-click on a person that shows only a first name.
3. Display the "info" window, if it is not already displayed, by clicking Cmd-i.
4. The Info window should show the full name of the person if the person was tagged from a Contacts entry.

This procedure is a lot of work, so it is not a replacement for simply being able to see the full name of a person under the Person's album or under a tagged face for a person, but at least this is a way to discover whether you actually named a person with only his/her first name, or if you named a person by using a name suggestion from your Contacts app.
