Hello,
That is handle directly by the HikaShop core (the field class) with the code
if($zone->zone_name_english != $zone->zone_name){
$title.=' ('.$zone->zone_name.')';
}
So if you want to remove the name of the country ; you'll have to edit an HikaShop core file (which is not recommended) or you can edit the countries to change their "zone_name" with the content of the "zone_name_english".
