Post detected and said it imported but not showing anywhere

Hi –
The plugin detected the posts on my fanpage.
I used the import now.
It said it succeeded.
But I dont see the comment added to my comments on the blog post.

I suspect this is because I am using a FB commenting system on the blog ?

Does the plugin only work if you are using the normal WP commenting system ?

Thanks – Dan V ~
