component/hikashop vs. /eshop

Hi,

I have upgraded to Business edition and have problem to display products when I click on product category in side module menu.
All products display correctly when I click on menu item Eshop in main menu
montemama.eu/index.php/eshop
But when I select a product category in menu in right column, I don´t get any results.
I have noticed, that there is a difference in URL which I get
montemama.eu/index.php/component/hikasho...-najmensich?Itemid=0
When I replace component/hikashop with /eshop, it works.
Could you, please, let me know what is wrong in my administration? Is there something with SEF?
Thank you!

EDIT: Problem solved, I have corrected canonical URL in all categories.
