Why are delivery errors not disappearing as I resolve them?

When selecting the Has errors filter in the Deliveries section, a search will generate all recorded errors for a product. This search won't account for any successful redeliveries or resolutions. To only see products that are still in error status, you can select Has unresolved errors. This selection does take successful re-delivery and resolutions into account. In this view, a search will no longer return a product that has since been ingested successfully.
