[Smush Pro] Smush Pro and missing product images in WooCommerce

I have installed and run Bulk Smush on our site https://zenesse.health and everything appears well except for the product images in WooCommerce which have all now lost their main product image and all gallery image thumbmnails. Now even if I replace the main product image, the thumbnails are still not showing. See: https://zenesse.health/shop/
Can you please have a look and advise?

Best regards,
