Ok. It's WAI 😐
(WAI stands for "Working as Intended,")
Thanks for reporting, I will get this fixed before 1.13.0
@alfazaz Me too, it is a bug, but in the meantime, you can select it and mark it as read, or mark all topics in the unread page as read
Edit: Nevermind, it doesn't go away
Yes, it's OK now. Thanks !
