Woo Commerce Blurred Images

Hi,
Ive started to set up Woo Commerce to replace my existing image print pages.
Ive noticed an issue with some product gallery images all becoming blurred which only happens when WP Image Zoom is activated.
Any advice would be appreciated I have read some support on this and checked the image sizes etc and plugin work perfectly on my other existing Print sales pages.
I noticed the plugin options allow tickboxes for Woo Commerce but I cant select these so I presume they are an upgrade feature.
Regards Simon
