Herk, I think your cards are upside down. I examined mine, and they are somewhat curved. Placing them into the latches from the top causes them to curve away from the fridge body, creating a less than positive connection and allowing the door to actually close nearly all the way. Feeding them in from the bottom, and snapping in place allows them to create a much more positive latch on the edge, which holds the door in proper position.
