Game wants to scrap my legendary cards?!

[WarGreymonAlfa]

I just logged in and when I wanted to use the deck builder the game gives me a prompt that it's about to scrap six legendary cards... I have my card collection set to premium focused and I know for a fact that I do NOT have 6 extra legendary cards. Worst still I have NO idea what the game wants to scrap. Anyone know what this is all about?

My settings for milling are premium focused. I just logged in the game and I get a prompt that the game wants to scrap a huge amount of cards including six legendary cards. I know I don't have six extra legendary cards and I don't know what the game wants to scrap. Is this a bug or is something happening that will demand the game to remove existing copies of cards I have for whatever reason?
