Ultimate Facebook comments not showin on Blogs mu Theme

Hi Ultimate Facebook is not showing or overriding the Comments on the theme Blogs mu.
I have checked the following
Use Facebook for comments
Override WordPress discussion settings
I DO NOT have a Caching Plugin active or installed (Yet)

the Comments box for WordPress is still showing
I have read a few threads on the subject a few gave up, a few fixed but did not say why, One had to install a plug in to disable comments then gave up. So I have no luck in my search Please Help.
the Pic is my Settings
