Hi,
Try to disable all third-party plugins that do not come bundled with our theme https://xstore.helpscoutdocs.com/article/36-included-plugins , and check how it works then.
Go to Appearance > Themes > install and activate Storefront theme and test if you have the same problem when the default WooCommerce theme is activated. Keep in mind that widgets (Appearance > Widgets) could be messed up after switching and you will need to place them back once enable XStore again.
Let me know if you have the mentioned problem when the default theme is activated.
Regards
