here is what I did to stop that:
Get rid of GCO calculating shipping, ensure it set to zen cart totals
Disable -- Free Shipping Options
Enable --FREE SHIPPING!
Any item that is free shipping must be selected by the item in the catalog.
I figured this out after a fee people got away with it, now it is correctly working, I also have USPS and UPS enabled in shipping module
Good luck
