There is another feature you should be aware of. AI provides suggestions in small batches, and it prefers to suggest only those that have higher probability of being correct. So, if for example it sees lots of “low hanging fruits” for just one of people, it may focus on suggesting those first. Then, after you confirm those and all “low hanging fruits” will be covered, it may attend to other people too. The goal is to simplify it for user, by ensuring user mostly confirms, instead of cherry-picking correct suggestions among false ones, which could be tiresome. The flip side is, that suggestions are not always evenly distributed among people in your gallery.
