You're not going to get the userlist output you want without creating a custom template for it. It's not a userlist within a field. It's fields within a field. So they will display as fields are expected to display on a userlist. You can find the template files for CB Field Groups at the below location.
/components/com_comprofiler/plugin/user/plug_cbfieldgroups/templates
CB Field Group includes several templates for different displays. Maybe the table template would make more sense for what you're wanting.
