Collectible Card Game Headquarters

I create a deck with the draft card, start a single duel in draft mode. Match starts, I choose the sets and pick the cards. After the last review the match doesn't start but a victory message appears. When continuing a new draft starts?

Do I miss something or is draft not working?

You may have encounter a bug if you meet it again please mention which of the 3 you selected: (1- ignore rarity or 2- enforce rarity or 3- singleton)and which 3 sets so we can check.

It is not fully automated but still my favourite mode.
