OS X Mountain Lion Notification Center not working.?

[dr1115]

I know for like Mail and twitter you have to have them on background for notifications to show but I have the facebook integration and none of my facebook notifications show up in the Notification center. I will go to facebook though and have new messages and requests and notifications. My mail has worked and my calendar and reminders have been working but I've yet to see any facebook or twitter notifications.
Yes they show up in both the System preferences > Notifications ; system preferences > security and privacy > privacy only thing is next to them in privacy they say "Apps that have requested access to (Facebook/Twitter) will appear here."
