Having just read through this thread in hopes of finding a fix for this weird problem, I am now dismayed: it's been going on for _years_ and they still haven't fixed it? Wow. It's seems pretty basic that a genealogy software program should get the ancestor's relationship correct (and by correct I mean listing my 28th great-grandfather as that instead of the husband of my first cousin 25 times removed).
I just wrote an email to email@example.com
as suggested. But I'm super-bummed there seems to be no way to fix it.
