So you might want to check your tools manufacturing Machine.
Basically, this game uses an item ID as "storage" for each item that needs something. The tools machine uses infrablocks. You might find it's in the machine. You'll need to dismantle it, to recover the blocks, or alternatively edit another location that has the same item ID. You may have to hunt around for where the item you increased the quantity of is located on your ship.
While annoying, it can be handy if you want to directly input a quantity into say a power generator, and modify that quantity, so your people do not have to carry the items to the machine.
I can verify that at least half of the Item ID list is correct, because I was working on something similar.
