category module link to nostyled page

-- HikaShop version -- : latest
-- Joomla version -- : latest

Hi,
I have two my web shops (HikaShop) connected in one. Now my customers will can order products from two web shops once (one login, one shopping cart, one account, ...). But these two online shops have totally different kinds of products, therefore, have different templates. I made an extra top menu, where each item refers to a separate section of the website:
1. Home (external url "mijnsite.com" - a link to ordinary index.php page, which connects all websites)
2. first shop - large (menu item alias - a link to the first shop main menu (horizontal menu) home page: All Categories page) associated with the first template,
3. second shop - small (menu item alias - a link to the second shop main menu (horizontal menu) home page: All Categories page) associated with the second template,
4. Blog (external url "mijnsite.com/blog/" - a link to a separate folder).

(2) and (3) are actually one big shop installed in 1 joomla folder.

In the small shop (3) there are two modules (HikaShop category modules) with the links to each category with the number of products in each category (joomla menu item does not show these numbers, so I chosed for HikaShop module with menu style instead joomla menu module, so I have two vertical menus, which are always automatically updated).

Everything works perfect, except these modules. The problem is when I press an item of this module, I get the page without template - a white page with content without style.

Does anyone know how I can connect these modules with corresponding template? Maybe there is a suitable code?

thanks, Vero

Sorry, sorry,

Just a stupid mistake: categories canonical url's not modified ....
