Minecraft version & Mod Version: Minecraft 1.12.2 Mod Version 1.7.4

Single player or Server: Single and Server

Describe the problem (what you were doing / what happened):
Items are duplicating on any remote that has a crafting grid. When items are placed into the crafting grid either by JEI or manual placement and shift-left-clicking on the produced item the item remains in the crafting grid and one is added to the storage system. Either removing and replacing an ingredient, Shift-clicking from JEI or closing and opening the remote resets the duplication allowing it to be repeated.

Crash log (if any):

I created a separate network with 64 Redstone and 64 sticks took half and placed in crafting grid

As seen here there is no reduction in material, but a Redstone Torch has been made.

I feel like im not doing this right. You said " shift-left-clicking on the produced item", but all that does is craft 64 of them.

All i did was make the 32 and 32 setup like you did. and shift left click is that right?

I have forge 2768, SSN 1.7.4,

Nevermind im dumb, previous comment was in the table.

Also bug does not happen if FastWorkbench is installed (such as skyfactory4) but with that removed i see it
