when you open your metal container, make sure it fills 14 spaces.
The item that you want to duplicate, make sure it is located on the 7th top row and the 7 bottom row. Then exit the metal container completely. Open your backpack. Do you recall the exact spot the items you want to duplicate were in the metal container? Well in the "grey area" to the right of your spaces, touch and hold until you see your item that you are trying to dup and slide it to the empty boxes in your backpack. Exit your back pack and do it again. You can do it on both top row and bottom row.
