[Smush Pro] Images not rendering in Woocommerce when activating Smush Pro

The Woocommerce are not showing up. The first instance can be seen on the home page bottom (catalog). The second instance is the large images on individual product pages. See Example: https://www.delbrio.com/product/original-rustic-galvanized-tissue-box-cover/

It may be somewhat related, but does Smush Pro conflict with SG Optimizer? SG Optimizer comes preloaded on my Siteground hosting.
