Gallery Image not filling container

Hi

We have updated woocommerce and this plugin and since then the image size in the container is not full width.

See example here: http://www.vacationista.co.za/portfolio/sandy-bay-beach-house-llandudno-3-bedroom/

Any ideas? We cannot change the image size in customizer as it’s not listed there.
