I am a returning player. When I first played MTG Arena, I (apparently) completed the green Colour Challenge and received the Starter Deck as a reward as normal when I first played. Now I came back and finished the rest of the Colour Challenges, did also receive the other Starter Decks, but they are shown in the Deck Editor grayed out, telling me I am missing some cards. Yet I can clone the decks and then play with the clones. It seems to me that I have the cards but the Deck builder hasn't noticed yet.

Also, when I try to play Alchemy, the button is a darkish orange and it can't be pressed. After switching to Standard Ranked, selecting a deck and switching back to Alchemy, the button is the normal bright orange. However, when I press it, nothing happens. Not sure if the game is butting out because I haven't unlocked everything yet or something.
