Looking through the code it looks like this is intended functionality to reduce the clutter in the admin screen. Here’s a little snippet so you can override that functionality.
add_filter( 'woocommerce_formatted_address_force_country_display', '__return_true' );
This only works in the bleeding edge version of WooCommerce – it should be included in 2.0.14
