Persisting Errors on Last Operation Status

Hello,
We are seeing errors from a failed backup almost a year ago that persist in the Last Operation Status area of the Polices. Although we re-ran the failed backups, the errors don’t go away as they usually do.

Does anyone know how to get rid of them? It’s just an annoyance, but we’d like not to have to check that policy every day just to make sure there isn’t something valid there.

Thanks,
Jeff
