Issue with images on products pages

Hello all,

I am having issues with the products page on my wordpress install, it seems to be showing the last image that was uploaded to the website, rather than the featured image for the product listed.

The product categories are working fine. I am using the latest versions of everything.

Links to the website:

If you need another infer please let me know.

Many thanks,

Andy
