Missing Cards from Collection

I purchased 3 of the same card from the auction house for the daily today. When hitting buy now, I sent 2 of 3 to my collection. The third I relisted  I went to edit lineup, added one of the 2 in collection to lineup. Then I clicked the card and sent to trade pile. I then added the final card to the lineup. I relisted the card in trade pile. Then when I went back to the lineup the third card was gone and it wasn't in collection. Massively annoying both because gamebreaker cards are expensive rn, and it makes doing the chore objectives harder.
