I tried to make a bunch ofChemical Duration Mechanism with a factory and its not working.. I keep getting the message that it made 0 items... Iput the exact ingredients in the ingredient hopper and it never makes a single Chem Duration Mech. Is this a bug?

make a junk scematic then add that to the fact, remove all the ingrediants then redeed it, place it again and try, it should work, factories are really buggy, I have to redeed after each item or it wont make anything
