We made some changes regarding this problem,
Can you edit the "YOUR_WEBSITE\administrator\components\com_hikashop\classes\shipping.php" file and change these lines :
$trans = JText::_(strtoupper(str_replace(' ','_',$value)));
if(strpos($trans,'%s')!==false){
$trans = JText::sprintf(strtoupper(str_replace(' ','_',$value)),$number);
}
if($trans!=$value){
$trans = $value;
}
$app = JFactory::getApplication();
$app->enqueueMessage($trans);
By :
$transKey = strtoupper(str_replace(' ','_',$value));
$trans = JText::_($transKey);
if(strpos($trans,'%s')!==false){
$trans = JText::sprintf($transKey,$number);
}
if($trans != $transKey){
$value = $trans;
}
$app = JFactory::getApplication();
$app->enqueueMessage($value);
Thanks
