Error on job upgrade

I made a under the mountain room to put all my storages in. I play with the map looking like this.

Here is the storage pic.

I had a cook staff and upgraded my farmer to cook and got this error.

This error didn’t repeat when I upgraded a worker to farmer after the cook was upgraded.
