Product image disappears

When I activated this plugin on my client’s site, it does take away the ability to purchase. It also removes the image from the single-product pages. Here is an example: https://www.chrisblevinswatercolors.com/product/cast-away/

These images only disappear when the Woocommerce Cataglog plugin is activated. How can we get the image(s) to appear on these single-product pages?

Thank you in advance for any help and details you can provide.
