[Plugin: Facebook Comments] Not all comment showing

Update,

I have discovered that the comments appear only for the account that is logged in in facebook with that browser.

For eg, if with my account i’m logged to facebook and than i go to my blog, i can see the comments that i posted to the blog using the faceboog plugin, bun than if i logout from facebook and i refresh my blog page, no comment are there anymore ??

update:

I have discovered that only my friend comments appears, non friends comments doesn’t appear, not even in the facebook moderation tool ?? I receive in facebook that a new comment have posted from the correct people (not a friend) i than click the notification and i go to the facebook moderation page but that comment is not there ??

I would like to add that in my privacy setting everyone can write to my wall, so i don’t know why this happen, help please ??

Integration is easy, but I do not see any comments appearing in Facebook afterwards. Tried several times, they are there in the blog but not in Facebook (not on my wall nor on the apps wall). Any help?
