For some reason, this question doesn't have a flag "as duplicate" option:
It has been put "on-hold" because the user was having a small problem with translation which only became clear once the answer was accepted. I have revised the question based on the accepted answer, but also need to flag it as duplicate because it's actually a duplicate of this question:
Is it because it's "on-hold"? If so, why can I not flag an "on-hold" question as duplicate?
