Purchase Order not sent out EDI

Good afternoon everyone, 

I have a couple of Purchase Orders who are going to a supplier that is set up for EDI. However, when I ran the Purchase Order outbound program were not picked up. 

When I queried off of it on PO_HEADERS_ALL I've noticed that it has a PRINT_COUNT of 1, and a print date of today. (Thereby disallowing it from EDI is my thought process). The EDI_PROCESSED_FLAG is still null as well. 

My question is, is since you are unable to check the print box on the Purchase Order Approve screen (EDI is picked, and you are unable to print it any other way), how was this print flag checked? We have called the EDI Vendor and they have not picked up these purchase orders, but have picked up other PO's from today (Verified that they were ftp'ed).
