Avatars in the imported comments

I have bought sa pro version. Import of the comments went fine. But.

When I look at the post, avatars are all mine – owner of the blog. Though the names are right. But when I look at the comments in the wordpress CP, avatars are from those people on FB who commented the post. How do I display right avatars?

THanks!
