Lucky Cat Bingo

In the Opulent Fruit Fest Bingo Jam, you have to daub 400 cells in Lucky Cat Bingo, I am not getting credit for the cells that I am daubing. I have played the 2-card game over and over, and in some cases have almost covered the cards, and when the game is over, it will say I only got two or three more cells instead of 30 or so. I should have been done with this challenge, but I am not even halfway.
