Remember what I said about other items from other mods being crafted but not consumed? If you uncraft those recipes, you don't get the item from the uncrafting table.
Then maybe it's been fixed, because when I try in Monster 1.1.1 (I know, there's 1.1.2 our already) I do get the squeezer and infusion stones back. Sorry I'm not testing latest versions these days, but I don't maintain Monster and I have no clue how to contact the Monster maintainers.
