Hi,
This means that the Itemid parameter is missing in the URLs generated by your products carousel module.
When a products listing module is a HikaShop content module, you have a "menu" option in the module so that you can select a menu item and the id of that menu item will be used in the Itemid parameter of the URLs so that when the SEF system of Joomla converts the URL in SEF it will use the alias of the menu item instead of component/hikashop
So either your module has such option, or you need to see with the developer of that module to add one.
