Inbox (2) (BB-8783)

Hi, currently I'm not able to view new messages, that were sent directly to me by another user.
I've received 2 emails with the content of these messages and there are 2 new indicated by Inbox (2) combo.
But when I navigate to Inbox by clicking on Inbox (2), I cannot see any messages there.
Is it a bug or some king of embarrassing behavior?
