What does the status "RETURNED UNPROCESSED" means while checking PWD?

Does anyone know what does the status “RETURNED UNPROCESSED” means while checking PWD case statu son DOL site?

Thanks

Hi did you get the PWD approved? What should I do if the PWD returned?

Hello, “Returned Unprocessed” means that the application is submitted without a current PWD that does not meet the requirements for an emergency waiver.
