Duplication bug/glitch

When crafting in and out of a crafting table, if you tap on an item tap in a blank space, then tap back on the first item, it will duplicate said item. It currently duplicates everything, including stacks of items.
The order of how it happens I will show in this list
1. Tap any item in the crafting menu
2. Tap any other blank space in the same crafting menu
3. Tap on the first space in step 1
It gets duplicated, in my case anyway. I can record my screen if needed and show it happening.
