Duplicate contribution

I sent a contribution #240917-153719-141000 which was refused for lack of evidence.

I wanted to update this contribution by adding a screenshot of the credits but each time, my contribution (e.g. #240917-152118-636000) is declined because “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.” Whereas there is no other contribution under review.

Coud you tell me how to proceed so that my contribution can be reviewed?
Thank you
