I am using Products Restricted Zones addon to restrict shipping certain items out of state.

So I have all the In-State Only items under category number 1; however, I do have subcategories under that.

Code:
Category 1
 |-> Sub Category 1_13
 |-> Sub Category 1_7
 |-> Sub Category 1_4
       |-> Sub Category 1_4_13
 |-> Sub Category 24
Inside addon configuration, I put:

This is to say only ship products under Category 1 to California.

This does not seem to work. I had a customer but an item from Sub Category 1_4_13 out of state.
