Featured image WooCommerce replaced screen size

After using cloudflare. The featured images of products on site https://frickin.nl are changed with product image after resizing screen. So the featured image appears on small mobile screen. Butt when the screen hits the tablet or desktop size the image is replaced by a image from the product gallery. How can this be solved?

Hi Otto,

I had some trouble replicating what you are describing, could you please capture for us some screenshots that show this issue?

Thanks!
