Season pass dissappeared?

I purchased the season pass for Battleborn on XB1 back when the game first launched. Received all the benefits such as the hero keys to purchase the new characters for free, but recently I have upgraded to the Xbox One S and now when I try to play battleborn and use a key to unlock Ernest it says I need to purchase the season pass again. I have proof of purchasing the season pass, but when I go to the marketplace on XB1 it says I need to pay $19.99? Help please?
