The International forum in the Addon's forum often shows me a new icon image but going into the forum I don't see anything with a new unread icon. If there are hidden folders/forums in there that I don't have access to then I think that's a bug and should not be showing me, if that's not the case then curious why only that forum seems to operate that way.

The other forums when shown with new unread topics does have unread topics as it should.

It's just the international forum - for the threads 7 series? There's no sub-forums there.
