[Bug]: Deleting a Coverage Record Resets the Filter

**Platform:** Map/Website

**Description:**
In Admin > Coverage:
Set a filter, then delete a record.  The record is deleted, but the Field Selector resets to "All Fields", resulting in a set of records that don't match the original filter.  You have to change the Field Selector back to what you need every time to keep deleting records.
