Please, enable default WooCommrce theme – Storefront, disable XStore Core plugin and check if you have the problem. Reply back in case problem persists with our theme only. If you see the same issue even with the official WooCommerce theme, please, check WooCommerce documentation and settings. Contact with WooCommerce support because we are able to provide support for issues related strictly to our theme.
