Bug in display of "useful with this" module

-- url of the page with the problem -- : www.boxspringshop.be
-- HikaShop version -- : 2.2.3
-- Joomla version -- :3.2.1
-- PHP version -- :5.3.3
-- Browser(s) name and version -- : Safari 7.0.1
-- Error-message(debug-mod must be tuned on) -- : Error_message

When I show related products, sometimes there is a problem with the display of the products..(see screenshot "Handig Hierbij"
But when I just look in the product listing, it's all fine...(second screenshot)? What can be the problem?

Hi,
Your problem is probably coming from a CSS issue, using some CSS code will probably do the job.

But I have a universal CSS line for the thumbnail boxes, which works fine for all the rest of the products in a listing display. And if it was due to CSS, it should happen with every box in that module, not sometimes working all fine, and the next page putting all text and price behind the image...Isn't it?

Thanks, here is the screenshot you've asked for. The strange thing is that I never filled in the image height in the backend and it used to work all fine...

Thank you very much! That was pretty stupid of me :/ I thought it was a malfunction in the PHP for displaying the thumbnails in the module, because sometimes it worked, other times not....Anyway, thank you very much!
