The slot order is in reverse. When items are piped in, they go first to the bottom drawer and then the top drawer. When you look at the drawers, Jade shows the slots in opposite order of what they visually are. The 1x2 is flipped and the 2x2 is also in a sort of backwards order; bottom right, bottom left, top right, top left.

I understand that maybe this is an opinion and the way that it is might not seem "backwards" to you, but it does seem backwards to me and it's the opposite of how Storage Drawers was. So it would be nice if this was a configuration.
