Good catch. It does look like the Utopia teams may not be appearing on the Manage My Team page. I have only 5 countries remaining which should show up in the third slot, including Utopia, but only the other four show up. And there are a total of only 18 teams in those four countries - there should be a lot more Utopia teams available to be picked at random to be listed there as a option for a flag I don't have yet.
