Here is a copy of my post back in August:
I had this problem too when I was trying to complete the L'Jarius Sneed set. My 5 players would NOT become unBND. Here's the workaround that I found.
1) Make sure that he's not in the current lineup. I had to change to a Lineup that does not use this player.
2) Unfavorite him. (if ANY Abilities, then Get Out, Return)
3) Refund. (if ANY Abilities, then Get Out, Return)
I had a problem because I had Closer on Kwity Paye. Even though it was not currently being used it wouldn't unBND him. I had to Upgrade and Refund him again.
The BUG seems to be that one can NOT refund ability training and downgrade to BND status at the same time. (Even if FREE ability, ie. Closer, NOT currently used.)
This workaround worked in August. I've used it multiple times since.
