[Plugin: Facebook Comments for WordPress] Duplicates the posts

Facebook comments for WordPress adds the comment box to the post pages. It looks good, BUT it duplicates the posts that is clicked on. And any new posts added get duplicated. So therefore the plugin is not usable! 🙁 too bad, everything else about it was running well.
