[Plugin: Facebook Comments] duplicate comments box

Hi, I’m looking to change the defuat positioning of the comments box on my theme by using the php shortcode (echo do_shortcode(‘[fbcomments]’);).

I’ve inserted this code where I want the comments to appear but now I have two instances of the comments box. Is the original supposed to be replaced by the new placement? If not do you know how to remove the original instance from appearing?

Thanks
