profile shipping details. country choice stuck at either usa or canada

Hi there
Iv set up a few fake users in my store. I am logging in and out testing paypal express, which is all working fine and working with sandbox.

However, I am loggin in as different users and I am trying to change some of the shipping addresses of the different user profiles to simulate store owners from different countries. On some of the profiles I have a full list of countries in the drop down box, and in others I only have the option of canada or usa.

Is this something to do with the original info put into the profile or something else I am missing.

edit
When I log in as superadmin and edit the same profile it reads the correct country (united kingdom) which I save, but it doesnt stick, because when I log in as the user it goes back to the choice of canada or the usa....weird
