HOw do I get Ultimate Facebook to work properly?

HI, I have the Ultimate Facebook plugin in KIND OF working but some kinks I can't figure out are this:

1) On the main page It always either says: enter your comment, or it just doesn't show anything about comments on the posts, regardless of how many comments there are.

2) When I go directly to a post, it also says: Leave a comment at the top instead of saying "6 comments" or whatever

3) The comments that happen on the site are not cross posted to Facebook.

4) It says I have 6 likes or whatever, at the end of this post: but I can't figure out WHO the people are who liked it, as it only shows me pictures of two of the "like-ers"
