Mac mail bug?

I've been having an issue where I have an 5 unread messages tag on my junkmail box in Mac Mail.

I have an iCloud account and am running OSX. 10.10.2

I've tried deleting all messages in my junkmail folder. The 5 unread email tag does NOT show up when logging into my icloud account through a web browser.

I've also tried removing and adding the icloud account in Mac Mail preferences....

Nothing seems to get read of the unread tag.

Any suggestions would be appreciated.
