Yeah if I had to guess it’s less of a bug and more of an oversight. I think they forgot human Serana can marry when they stripped it from Vampire Serana. If that seems weird I wouldn’t be surprised if the two versions are effectively different NPCs with a shared dialogue tree. Though I have no clue if you could even do this weirdness on the original PC or PS3 versions of Skyrim.
