The goods on the shelves are placed in a chaotic order, next to the face cream there is dishwashing detergent, and a jar of jam is next to washing powder, which is completely unacceptable. Before you can re-categorize your items, you need to use Shelf Shift Match to clear all the shelves. You can only remove three identical objects at the same time. Place them on one shelf and they will all disappear at once. There may be others behind the items on a usable shelf; you will see their dark silhouettes. Products will appear if you remove the first row in Shelf Shift Match.
