I'm guessing this is just another one of Skyrim's bugs but I wanted to make sure. For almost all NPCs, dialogue that I have already gone through with them constantly resets and the dialogue option becomes bold (not grayed out) again, as if it's a new topic we haven't discussed before. It confuses me because I'm like, "Wait, didn't I meet this character already? Why are all the dialogue options bold again?" Is this happening to you guys as well?
