CSS problems after update

-- url of the page with the problem -- : www.theodoor.be/index.php/webshop
-- HikaShop version -- : 3.0.1
-- Joomla version -- : 3.6.5
-- PHP version -- : 7
-- Browser(s) name and version -- : Firefox 52.0.2

Getting one column instead of three columns. And I don't have ..

.hikashop_subcategories div.hikashop_category, .hikashop_products_listing div.hikashop_product {
float: left;
width:100%;
}

in my code. So must be another solution.

Second problem is the filter_title and filter_value_container. They - as you can see - are not proper aligned anymore.

Greetings,
