Listing internationally on American and I keep receiving the pop up "US destination address field cannot be left blank"

I cannot figure this out.
I'm booking in and out of the same US cities into the same International destination. I called the non rev line and was told they have no idea what it means.
Anyone else come across this? Anyone have any ideas? I rebooted my computer, shut down the non rev site brought it back up and I'm still getting the same error response...
Any help would be appreciated.
