Just a little more digging, forgoing sleep for research, and I found a solution. Since there are only 12, I don't need to delete them (although that would be best), I cam just close them. I used this article: http://www.symantec.com/docs/TECH137507 and modified the SQL query to be this:
-- The following SQL script changes orphan tickets to Closed.
-- Before using, it is recommended to back up the ProcessManager database before proceeding.
USE ProcessManager
--Note: Change the 'ReportProcessID' value to the processid (ticket number) you wish to close
--For example, 'IM-000400'
UPDATE [ProcessManager].[dbo].[ReportProcess]
SET [Result] = 'Closed'
WHERE ReportProcessID = 'ReportProcessID'
UPDATE [ProcessManager].[dbo].[ServiceDeskIncidentManagement]
SET [close_code] = 'Closed Orphan'
WHERE Process_ID = 'ReportProcessID'
-- END SCRIPT
This seems to work ok for me now.
