Maybe a glitch??

Both the Backlit Chic Wall Shelf and the Gentle Vibes Wall Shelf have areas that we're supposed to be able to add smaller items on. But the little squares are not on the shelves, they're on the floor and there is no way to add other items onto it. 

Anyone else have this issue? Or know if there is a fix??

Thank you for any help I can get! It's been bothering me!
