Bug Deck Builder

After the first tutorial boss I get to the deck builder telling me that I have unlocked the first 8 codex but I cannot select them. They are all turned off. I can only right click on anyone of them, this action show me the cards but that’s all. I am stucked as I cannot build my first deck…please solve this issue

So do I. The deck builder tell me to pick 30 cards, but I can only take 4. After that, no matter what clic I do, nothing happens.
(sorry for my english, I’m french)

Mine does not let me pick any card

This is a problem a small group of users have been experiencing since the server maintenance on Friday. We deeply apologize for this, but we cannot fix it until Monday - it is a known issue at this time.
