Products are not displayed after update to HikaShop 4.0.3

-- HikaShop version -- : 4.0.3
-- Joomla version -- : 3.9.4
-- PHP version -- : 5.5.9-1ubuntu4.27
-- Browser(s) name and version -- : Firefox

After upgrading to HikaShop 4.0.3 my website only shows the product categories, but does not show the products after clicking on the categories.
However if I manualy paste the canonical url of the product in the browser it display the product correctly.
Everything was working properly until before the HikaShop verion upgrade.

I got the problem solved by myself by editing the default menu that holds the display of hikashop.
In the 'Category Options' I changed Show Image to 'Yes', and the products started to display, but with the category picture on the top.
Then I changed the Show Image back to 'No', and hikashop started to behave as per normal.
