There was a recent thread where a sling user couldn't get it working until dish tech support "swapped" which receiver was listed prime and which was listed secondary in his account file. Perhaps when the customer accounts data base was designed nobody thought there any reason which equipment was listed where. Then sling made it important that when a customers DRA app accessed a user file it had direct which receiver was sling enabled.
This makes me believe issues like yours can get cleared with a very sharp tech support tech. Give support a chanceeither by phone or on line chat, both can get you in touch with some smart people.
