Actually, the images are not zoomed it just shows the second image on hover nothing else. The images you are using for the products are not the same size you used different size images for products and by default, WooCommerce compress the image sizes so that’s why the images look cropped or zoomed on hover. Like this I show you in the video: https://streamable.com/huqv6b If you open the hover image on a new tab of the browser you will see the image then you will understand that the image is not zoomed it just shows the next image of the product you added. To set the images to appear complete without cropping kindly use the same size images on all the products for a good user experience.
