Yesterday, I asked the question Will the pluralization issue in number of bookmarks on list of bountied questions in user profile page be fixed at some point?, which in its original revision reported a bug. That bug was already reported in an answer to the announcement New responsive Activity page, and had been marked as status-planned by a staff member, so as such my question (correctly) got marked as a duplicate.
Having noticed the answer and seeing that the prior report had been tagged as planned more than two months ago, I edited my question into a different one, asking for its current status and expressing concern that it ended up falling off staff's radar (especially since the marking was right before the holiday code freeze). As it's an entirely different question, and no longer simply reports the same issue as in the answer, I believe the edited question should be reopened.
However, reopen reviewers still deemed that my question was a duplicate. Additionally, the edited question got a significantly worse reception from voters than the original question.
What can I do to improve the question so it's of higher quality?
Also, what can I do to have it reopened since it's no longer a duplicate? Can the reviewers please explain why they believe the question is still a duplicate, even though it's no longer simply reporting the same issue?
(The reviewers chose explicitly that the question was a duplicate, not simply that the original close reason wasn't resolved or some other close reason, which means they believe my edited question is still a duplicate.)
To be clear, the edited question has a different goal from the original question. It's asking about why a report marked as planned still hasn't been fixed, and asks if it's still on the team's radar or if it ended up falling through the cracks, which may have happened since the winter holiday was right after the marking. Had the answer been marked as deferred or even not received an official response, I would have simply not edited the question and agreed that it was a duplicate.
Update: I removed all parts of the question asking for the original report to be fixed, and made it solely focus on the report's current position in the queue. I understand that that may have an implicit undertone of "please fix this", but that's not what I'm asking: I just want to know the current plan to fix it. "We plan on fixing this 10 years from now" is a perfectly valid answer to the question. I made the edit and requested a re-review, but reviewers still unanimously rejected the request as "original close reason wasn't resolved": I'd like to know why, and what exact edit is needed to resolve it and make my question unique.
