Facebook Notifications Bug In Hub??

Can anyone else possibly try and recreate an issue I'm having?

I've set FB to NOT show up in the hub.

I get a new FB notification. I swipe to the FB icon in hub, and read the notification (changes from bright blue to gray). = Read

I go back to the Main Hub messages list and want to look at all my unread EMAIL (only things I have in the Hub main list)

I hit "S", scroll down to Unread, it shows all my unread email, but ALSO shows all the greyed out FB notifications. I have to actually delete them to get them to go away from the "Unread" search.

Thanks in advance if anyone tests this out.
