Wondering if your possible match is working?
Here are two people that names and births are alike. The program does not bring them up as possible match.
I would assume that date and name being the same, or similar, would make it a possible match?
If not showing up as a duplicate try searching on similar names. often the 2nd name will crop up there. If they are the same person you can merge them0
The algorithm weights relationships pretty heavily, and the two profiles are clearly coming at the person from opposite ends -- the one has a wife and children but no parents, the other has parents and siblings but no spouse or children. In my experience, these sorts of duplicates are rarely flagged by the algorithm until/unless at least one of the other relationships gets added to one of the profiles -- and I think this is generally a good thing.
(Having the same name and same birth year doesn't really say anything. I recently found an ancestor who remarried after her first husband died. Her new husband had exactly the same name as her first, and was basically the same age.)0
