TOTW cards turning BND

Hey, 

I was wondering if anyone would have an answer for me, I bought a bunch of 92 team of the weeks from the auction house. I put them in my cup chase game for my team of the week objectives and then when I go to take them out to trade them in for a star of the month, all of them are just BND, which seems almost impossible because I bought them from the auction house. If anyone could give me an answer? It would be much appreciated.
