I am seeing the
duplicate of... option twice in the flagging dialog. In the initial dialog and it appears once again after you press
should be closed.. Is this supposed to be like this and why?
We put it in two places to help people find it.
Duplicate is a bit of a weird option. Most of the other close reasons boil down to "this cannot or should not be answered" - duplicate is "this is already answered".
So folks don't necessarily look for it in the close options.
