Hello, Pablostevens,
Thank you for reaching out. Unfortunately, without a URL to the product page, we are unable to verify the issue. Additionally, without access to the WordPress admin, we are unable to check your settings. If the issue is not related to the theme activated on your site, as you mentioned it persists even with Storefront, we recommend contacting the WooCommerce plugin support team at – https://wordpress.org/support/plugin/woocommerce/.
Kind Regards,
8theme team
