I've never had more than one hint displayed, either. Frostfreedet, are multiple Shared Ancestor Hints something that you've seen recently? Maybe it's one of the new changes they're trying out with hints, but I just checked one of double-matches and I only see one hint. (And this is even one of the few matches where Ancestry is showing the leaf icon. Most of my SAHs still don't have one.)
Like I described above, my second hint only showed up when I altered the first one to a different surname ("Zzzzzz"), effectively removing it.
(I'm speaking exclusively of DNA hints, not the usual hints, in case there's been some misunderstanding.)
