On Meta sites we can close a question as a duplicate of another question which has no answers.
Which makes the current duplicate message incorrect:
marked as duplicate by USER X hours ago
This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.
At the time of writing, this (dupe) question is closed as a dupe of this question which has no answers, but the close reason is as above (stating "already has answers").
This is for Meta sites only, main sites are different as you cannot close as duplicate if the supposed dupe question has no answers.
