Auto-complete deck

I have a deck consisting of cards, but I only own some of them, therefore when I went into the “play” menu, it came up with a button on the deck called “Click to complete”, and when I press it, it comes up with this message: “Incomplete deck You are 44 cards short of a full deck. Do you want to finish the deck automatically?”. As far as I remember, there are only 30 cards in each deck, and since I already have 8 of the cards for the deck, shouldn’t I say “22 cards short…”?
