Feature Image not zooming

I’m using the Divi theme and added the image zoom plugin to woocommerce. All of the gallery images are working as expected, but the feature image on each product page appears with the roll-over hand icon and does not zoom. When you select a gallery image it replaces the feature image and then they all work. How can I enable the zoom on the feature image?
