Tax Display in Cart

-- HikaShop version -- : 2.2
-- Joomla version -- : 1.5

After migration to V2.2, the in the checkout the line taxes shows the "MWSt Deutschland", so in general terms TAXES COUNTRY. However to comply with regulations it must read "enth. MWSt (19%)".

In my langugage file I defined <TAXES="enth. MWSt (19%).">, however this does not change the display to the correct term, it still says MWSt Deutschland. What am I missing? I guess the code snippet causing the issues is in CHECKOUT>CART php file. I figures it would be in these lines?

if(bccomp($taxes,0,5)){
if($this->config->get('detailed_tax_display') && isset($this->full_total->prices[0]->taxes)) {
foreach($this->full_total->prices[0]->taxes as $tax) {
?>
<tr>
<?php if($this->params->get('show_cart_image')) echo '<td></td>'; ?>
<td>
</td>
<td>
</td>
<td id="hikashop_checkout_cart_tax_title" class="hikashop_cart_tax_title hikashop_cart_title">
<?php echo $tax->tax_namekey; ?>
</td>
<td class="hikashop_cart_tax_value">
<span class="hikashop_checkout_cart_taxes">
<?php
echo $this->currencyHelper->format($tax->tax_amount,$this->full_total->prices[0]->price_currency_id);
?>
</span>
</td>
</tr>
<?php
}
} else {
?>
<tr>
<?php if($this->params->get('show_cart_image')) echo '<td></td>'; ?>
<td>
</td>
<td>
</td>
<td id="hikashop_checkout_cart_tax_title" class="hikashop_cart_tax_title hikashop_cart_title">
<?php echo JText::_('TAXES'); ?>
</td>
<td class="hikashop_cart_tax_value">
<span class="hikashop_checkout_cart_taxes">
<?php
echo $this->currencyHelper->format($taxes,$this->full_total->prices[0]->price_currency_id);
?>
</span>
</td>
</tr>
