Not sure if this is linked, but when registering a new user and entering the address details there is no option to select the country.
Looking at the Localisation, Countries, United Kingdom, the address format is currently:
firstname lastname
company
vat_number
address1
address2
postcode city
Country:name
phone
phone_mobile
however, as soon as I save it it reverts to this:
firstname lastname
company
vat_number
address1
address2
postcode city
Country?
phone
phone_mobile
