Gateway Network Remnants

The six gateway networks in the image with errors do not exist. Is there anyway to remove the items from this status page? Some background follows below.

There used to be a gateway network between NARS-TOW-IGN1 (8.1) and Prod1 (7.9). It was deleted a week ago. Redundancy was enabled on NARS-TOW-IGN1 today with the backup node being NARS-TOW-IGN2. At some point in the past Prod1 was the primary server in a redundant pair. The gateway network between NARS-TOW-IGN1 and Prod1 was created AFTER the Prod1 backup server was taken offline. The redundancy settings on Prod1 were never changed to from Master to Independent.
