step by step to the problem:
(with Canada + US already installed)
import United Kingdom
remove Canada
remove US
Zone field is blank.
another bug:
above steps+
import US (again)
- Zones are working ok.
BUT if I disable US (not remove)
Country will show "United Kingdom" but Zone has all the US states in the dropdown menu.
update:
this behavior will stop if i go to Store settings and on the Contact settings page press Save.
(obviously the only country is UK)
(beta 7)
