Flat Rate Shipping Geo-Zone Issue

Hi Guys,

Ive got a problem, basically i wanted to offer free shipping on a specific category to UK buyers only.
So ive setup my geo-zones, one for UK only and another with all the other countries added to it.

However when i go to flat rate, set the value to 0, set geozone to the uk only one, and then add all products from just one category and enable "inclusive" and save.
I then checkout through UK and it works great however it also appears for every other country/zone once selected.

Can someone help please?

What version of OpenCart are you using? I don't believe there's an officially supported solution to restrict by category, just Q's mod for 1.4.x in the forums. It's possible there's a bug in that code.

If you want a commercial solution that works, you could use Category-Based Shipping.
