Sorry for my late reply but I had my hands full in getting the new webshop online:-)
Meanwhile one of our customers encountered the same problem I described so it is not related to some problem with GEOIP or something. For me everything is fine (I am in Belgium and the shipping providers I created for Zone Belgium show up as expected). Our Dutch customer however got the same problem, she only saw one shipping provider while for Holland I have created about 6 different options. The only one showing up is not related to what I defined for Zone Netherlands.
After activating debug information for the shipping part of Woocommerce I noticed that whatever zone I would try, except for Belgium, the Woocommerce shipping module would take Bulgaria all the time. It is a country we ship to but I hadn’t defined it there. I tried to add a Bulgaria zone but Woocommerce wouldn’t show me Bulgaria as a country so I picked Europe instead. And there came the problem from. I just added Bulgaria to our approved country list and now it does show up with the countries when creating a new zone and I can create the shipping providers for Bulgaria. So definitely not a theme problem but Woocommerce I assume. I have no idea why it breaks all the other defined zone definitions, with legit countries, and picks the one where I set the zone wider than one country. Thanks for your help of course!
