I can't get any Facebook Comments to show up?

I'm trying to use the Facebook Comments option with this plugin and have all the correct checkboxes ticked but it looks like the post is still trying to use normal Wordpress comments. Also, I've tried importing comments and no comments come into the system.

I have a couple questions:
1. Why is this happening?
2. Do I need to have the "auto post to Facebook" feature enabled for the Facebook Comments to work correctly?

Thank you!
