Images not syncing

Hello,
I am having an issue with my product images not syncing. I am using the pro version of the plugin and everything else is working perfectly. I can sync all other fields and export image links without an issue. I have tried multiple image files hosted on my site and off, changed the formatting in the GSheet of the image cell, removed the hyperlink, nothing seems to be working.

Also is there a way of uploading images to the featured image and gallery seperately?

Thanks for your help.
