Why do all comments on the site appear on my new user registration page?

Hi

Wondering whether anyone can solve this one for me..

On my site registration page, I appear to get all comments which should appear on the pages/posts they were submitted to (and they do) also appear at the bottom of my registration page.

Please see http:// http://www.thehouseofdog .co.uk / register/

Any clues as to why this is happening?

Thanks
