Posts on my Facebook page are not showing comments correctly on my site

Hi,

My Facebook fan page https://www.facebook.com/ourdreamspace does not correctly show comments for Facebook linked blog posts. Perhaps this is tied to a more simple and seemingly related problem where some FB comments show up on top of the more standard looking comments. See the two non-standard comments that occur before the standard comments at bottom of this page http://dreamspace.is/the-dream-of-climate-change/

PS I have granted access to my site.

Thanks for your prompt response : )
