Advance Parole

I had filed for regular AP that USCIS agreed to expedite. While it was being expedited I got an emergency AP. I had confirmed with two officers at the field office that the emergency AP would not interfere with the processing of regular AP. Was even told that if I need to stay overseas beyond the expiration of emergency AP then I would need to have the physical regular AP on hand. And, at the port of entry I was told to tell the officer that I left on e AP and then that am using the regular AP to get back.

However, the service center sent EAD only and not a combo card. The reason I have been told is that they will not issue regular AP when on e AP. That I would need to be back before e AP expires and then surrender the e AP to the service center.

This has been very confusing. My whole plan was based on the fact that the officers at the field office assured that the processing of the regular AP (expedite) would not be affected by e AP. My lawyer also confirmed on that. But the officer at the service center chose to think differently?

Does any one of you have any ideas on how to proceed? Obviously, someone is wrong here and I need to know who. If it is the service center then is there any article that I can reference to have them reconsider to issue the regular AP?
