I believe that the OP will find that when he registered the card in the second program it was removed from the first program. Indeed this is what happened to me. I was registered in the UA program but decided to accumulate miles with AA raather than UA so I registered the same card with the AAdvantage program. That card was automatically removed by the system from the United Mileage Plus program. If you only a re one credit card they make it so that you can only be in one program at a time. Otherwise you could double dip.
