How to remove decoration placed in store

[Bread-kun]

Hey so I placed some items during the tutorial that block some windows. I want to pick them up and remove them but I can not find a single way how to do it. Or even to just move them.

It's kind of tricky when you first try it out, but try to go on the edit menu and on each tab you can edit the different items per category, So one section for items on sale, another for the display themselves....

In this case, go to the backpack tab selected and try to move the items on the floor
