Categories & Products Listing DIV no longer respected after upgrade to 4.2.2

-- HikaShop version -- : 4.2.2
-- Joomla version -- : 3.9.13
-- PHP version -- : 7.1.14
-- Browser(s) name and version -- : Firefox 70.0.1
-- Error-message(debug-mod must be tuned on) -- : none

I have upgraded Hikashop from 2.6 to the latest 4.2.2 (Business).

The divs (3x7) layout used to be displayed correctly on both Categories and Products listing pages, but now both pages show on single column only.

I do not have template override files for either view.

I had to modified the css as below:

.hikashop_subcategories div.hikashop_category, .hikashop_products_listing div.hikashop_product {
width: 33% !important;
}

Is this the only solution or was I missing a setting somewhere?

Those codes you highlighted in red are what I manually injected in the template css in order for the pages to correctly display my products.

Please see the screenshot of the Hikashop product page while using the Joomla default Protostar (same broken listing style).

Thanks, that did the trick.
