Copying cluster snapshots to another region shows an error message

Hi, I'm trying to create a copy of an Aurora PostgreSQL cluster snapshot in a different region using the aws cli, I was able to do it five times, but now I'm getting the error message Cannot copy more than 5 snapshots concurrently to the same region. I suspect that the problem was that I deleted those snapshots while they were being copied and for some reason the status was never updated.

Question:

do I have to contact the technical support so that they can update the status of the snapshots in the region or is there a way to clean up the snapshots that were deleted before copy them?
