What fop2 version are you using? 2.21 beta includes a workaround for ghost park calls that get there when you abort an attendant transfer to the parking lot. Perhaps that is the issue you are having, you might want to try with 2.21 beta, the link to download is in the announcement forum
Best regards,
Found a post over on one of the other boards and got it fixed up. Thanks though. My issue was with the manager permissions or call events. I found a post here in one of the other boards.
