If a question is closed as a duplication, I know how to petition it to be reopened.
However, there is no way to remove "This question may already have an answer here" from my view.
Git revert certain files was not closed, yet for the rest of eternity I will come here and think that it is a duplicate.
Is there a deliberate reason that this never goes away? It seems strange that only by closing and reopening the question would that disappear.
There very much is a way for the notice to vanish:
If the close votes expire, it will melt away for all. If it gets closed, then everyone will see it.
Once all close votes have expired, the notice should disappear:
Close votes age away harmlessly after 4 days if the threshold is not reached. Each new close vote resets the timer, and close votes only start expiring if the question has had 100 views.
As the question you're referring to was asked less than 4 days ago, it's safe to assume the close votes have not expired yet.
On top of that, any user with the cast close and reopen votes privilege can see the current close vote count. The asker themself (that's you!) can also see the current close vote count (and cast their own close and reopen votes) if they have the view close votes privilege.
active to me), because nobody reviewed. If you want it go away, I think all you need is to vote Leave Open. Since you're a moderator over there, this will likely clear it - or, if it won't, then just close and reopen
