Declined submission - False Duplicate / Pending Review loop

I am writing to provide feedback and request assistance regarding a submission that was declined for the second time with the reason: "The item you have submitted is exactly the same as a submission that you or another user have already entered, which is still pending review by our staff."
I guess this might be an automation problem.

The most efficient approach would be for the reviewer to handle the update immediately clearing the pending queue so the correct data can be published.

Simply rejecting the update under the guise of a duplicate—without actually resolving the issue on the live page—creates a loop that prevents from keeping the page accurate. And it doesn't provide any real explanation about the rejection, if there is actually a reason for that.

Is there a way to prevent this from happening?
