Garrus Romance Bug?

So I replayed ME2 awhile ago for ME3, and I romanced Garrus like I always do, but his dialogue now loops? Specifically his 'do some research'. I got the romance scene, beat the game, go talk to him again only to get the same 'do some research' talk instead of the 'I'll think about what we talked about' dialogue. Is this a bug, I can't seem to get any answers.

note: Since the technical support threads have been closed, I just copied and pasted my question here which has yet to be answered.
