Search not working properly

-- url of the page with the problem -- : 181.224.136.115/~accura84/
-- HikaShop version -- : HikaShop [1405171505]
-- Joomla version -- : Joomla! 2.5.22
-- PHP version -- : 5.3.28
-- Browser(s) name and version -- : Firefox 30.0
-- Error-message(debug-mod must be tuned on) -- : Error_message

Basically, when I navigate to a specific menu item and select a category, it displays all of those products within that category, but if I do a search for the name of that product, it will generate the search results correctly, but when you click the categories in the search results, it doesn't display the products.

For example:
In the first attachment you can see the Coding Tapes, take note of the Breadcrumbs.
In the second attachment you can see that after searching for "Coding tapes" it has generated 3 different categories, which is correct.
In the third attachment you can see that once you click the first result, there are no products, please note the Breadcrumbs.

Any ideas?
