Issue witch NPC camp cooking, batch size fixed to zero

So I’ve had an issue with my NPC camp. The cooking used to work fine, but now it’s bugged. If I have the ingredients, I can ask for something to be cooked, but batch size seems fixed at 0. (See screenshot where I attempt to have come cooked meat cooked.

Mmmmh, strangely enough, testing some more I was able to assign a NPC to make starch from cattail.
