Hikashop Images - showing other products

-- url of the page with the problem -- : joomla.templaza.net/dekor/index.php/shop...tegories#prettyPhoto
-- HikaShop version -- : 2.6.3
-- Joomla version -- : 3.5.1

Hi,

If you go to the following site template...

joomla.templaza.net/dekor/index.php/shop...tegories#prettyPhoto

Click on the heart in the center of the item in the top left (the Duis quam urna) black chair. This will show the image of the product. This is correct.

Click on the heart on any of the other items. It will show thumbnail images that you can view from all the 6 products shown on the page. This isn't correct.

Is this a feature of Hikashop (that I can switch off), or a problem with this template?

Hope you can advise so I know where to follow this issue up.

Thx.
