Carousel effect problem

-- HikaShop version -- : 2.6.4
-- Joomla version -- : 3.5
-- PHP version -- : 5.5.12

Hi,
I am using the content module with Carousel options all setting copied from the hikashop demoside HikashopEffect(Three products in a fade).
The effect was good only the description didn't show up when hover.
My url is : www.likeego.com , and the test block is a neglect at the footer of my home page.
Could you direct me what could be the problem?

Best regards
Scott

Hi Nicolas,
Thanks, now it can be shown correctly.
I remarked some code, but I think there should be a better way for this, just I don't know how to set "config->get('show_description_listing',0)".
Following is the code that I remarked:
<!-- PRODUCT DESCRIPTION -->
<?php //if($this->config->get('show_description_listing',0)){ ?>
<div class="hikashop_product_description">
<?php
echo preg_replace('#<hr *id="system-readmore" */>.*#is','',$this->row->product_description);
?>
</div>
<?php //} ?>
It must be somewhere in the hikashop configuration, could you point it out for me?
Thanks

Best regards
Scott
