how do you remove a name from the autofill suggestion list?

Photos keeps suggesting names for faces in photos when I've just typed 2 letters. the names suggested may never have been identified in a photo; e.g. sometimes I had gotten an e-mail from them. ONCE. or they may have been in my contacts list but then deleted. (e.g. old job from 10 years ago).

having names of people I'm not in contact with makes the list longer and often prolongs the process of finding the CORRECT name of the person I want to identify in the photo.
