Category and Product blocks behave strangely

-- url of the page with the problem -- : semillascantueso.com/shop/categoria/creacion-de-rocallas
-- HikaShop version -- : 3.1.1
-- Joomla version -- : 3.7.2
-- PHP version -- : 7.0.19
-- Browser(s) name and version -- : Firefox 53.0.3

After updating to Hikashop 3.1.1 the number of products per line in my category and product listings are apparently random. I've set 5 categories and products per line in my Hikashop menu entry, but some lines show 5, other 1, 2 or 3. Also, the lines that don't show 5 items, are randomly aligned right or left.

I'm not sure this issue is limited to 3.1.1. I recall having similar problems that went away after some css tweaks I did. But the old custom CSS I worked with didn't work ok after updating to 3.1.1 so I went back to the default.

So, I'm using the default css and no css for styles.

The issue can be seen on the shop homepage: semillascantueso.com/shop (category listing)
and on product listings like this one: semillascantueso.com/shop/categoria/revegetacion

Disabling Infinite scroll does not solve this problem, by the way.

Any help would be very welcome.
Thanks in advance.

Hi,

Thanks for looking into this. I just checked with another browser and could not reproduce the problem. This is happening to me in Firefox. For testing purposes I disabled all plugins and used a new, clean profile. Still shows up like this:

What browser are you using?

That worked! Thank you!
