Hello There,
Thanks for updating in!
I have resolved the issue by installing a child theme and added this custom code in the child theme’s functions.php file
// Remove product gallery slider and gallery zoom
// =============================================================================
add_action( 'after_setup_theme', 'remove_woo_three_support', 11 );
function remove_woo_three_support() {
remove_theme_support( 'wc-product-gallery-zoom' );
remove_theme_support( 'wc-product-gallery-slider' );
}
// =============================================================================
Please check your site now.
This code will remove the WooCommerce product gallery slider and the gallery zoom. If you remove this code, you will see the previous issue as shown in your screenshot. If you want to resize the dimensions of the thumbnails, please go to WooCommerce > Settings > Products > Displays > Product images. After changing, please regenerate the thumbnails and then clear the cache again. It might also be good to disable the Photon module in Jetpack because it is caching the images.

Hope this helps.
