I added a profile for Ray Nash Studt (Studt-73) several months ago via a GEDCOM upload. A couple of days ago, I discovered there is a duplicate Ray Nash Studt (Studt-39). The two have the same full name with the exact same spelling and the same birth year. I was surprised, because I try to be very careful about comparing profiles when I'm adding people. But there it is, so I clicked on matches from Studt-39 to propose a merge.
The only potential match that was offered from the Studt-39 profile page was to Ray Stitt (Stitt-39) with no dates. I tried again to find the match from the Studt-73 page. I was offered matches to Stitt-39 again, Stout-1020, and Steed-1959.
I ran another search for potential matches from the general "Find...Matches" page with very loose parameters and asking to include any rejected matches. They still don't come up as a potential match (and this confirms I didn't accidentally reject it when I uploaded).
I have been able to propose a merge of the two profiles by just going to the general "Matches & Merges" page and typing in the two profile numbers. That is not the problem.
With the same exact full name and birth year, these two should be showing up as potential matches--especially when profiles that don't match either the name or the birth year are being offered as possible matches. And when you click on matches from each profile, the list of potential matches should be the same!
This seems like a glitch in the match programming.
