Facebook comment box conflict with WordPress comment box

Hi,

I decided to remove Comment plus and use Facebook comment included in Ultimate Facebook.

My issue is simple : After activated Facebook comment box feature inside Ultimate Facebook setting I have 2 boxes comments.

- Facebook comment
- WP comment

How to merge it or how to remove WP comment ?
