food warehouse is not working properly

The “Ration Box” and “Refrigerator” are just warehouses, the same as the “Storage Bin”, but the “Storage Bin” creates a storage order, and the “Ration Box” and “Refrigerator” create a purchase order.
It seems to me that for the Ration Box, Refrigerator and Storage Bin, it would be right to create a storage order.
ps. sorry for google translation
