Bug free deck hearthstone

Hello, I found a bug after the last patch update. As returning player my account is entitled with the free deck, the problem is that I got the deck but without having the possibility to choose it. I wanted to pick the mage deck but after the initial presentation of the new update when it came to the deck selection that phase was skipped and I found the rogue deck added to my collection.

Is there a way to repeat the selection or adding somehow the missing cards of the mage deck to correct the problem?
I hope you will be able to solve it! Thank you!
