My duels is broken

I had a 6 win 2 loss deck, a shaman. I logged is later and was prompted to start a new run
I selected mage and then choose starting items and hero power, then was prompted to build a deck, but my old shaman deck was already there, and it says I have 44 of 16 cards selected. I cannot add or remove cards or retire the run.

Also, I stopped being able to disenchant any cards at the same time. Neither mass disenchant or individual disenchant works.
