Two identical name suggestions for People in Photos

I see what you mean now... I often get those "contact" suggestions.

It appears you never selected the contact name to identify the person in the photo, since the two identical names don't appear in your people album. It simply offers the suggestion since it is the same name as in your contacts (it's not a bug... it's a feature!).

It is annoying and easy to select the wrong name, which creates a 2nd person with the same name. Unfortunately, Photos often creates a 2nd person with the same name even when their name is NOT in the contacts (but that is a different issue).

You can try to make the contact name slightly different (e.g. use a nickname, or even add a middle initial). I haven't tried that , but it may work.

This is an irritating and common issue with Photos.

The easiest way to solve this issue is in the "Peoples" album. There should be three people with the same name. Simply "drag" the duplicates onto the person you want. There will be a dialog box asking you to confirm that you want to combine these people.

I found that photos is creating frequently a second or third person with the same name, when I do not click a name from the list of suggested names, but type a name into the name field below the face.

It helps to make the key photos in the People album very distinctive, so I can recognise the correct name by the icon in the list of names and click onto one of the the suggested names.

Photos also creates a new person with the same name when you add a name before the suggestions appear (like when you paste a name from the clipboard). I paste names routinely and I constantly have to merge the duplicates, which can be a hassle since the you can no longer sort people in the "People" album alphabetically. I have 2000 "people" so they can be hard to find!
