Hello,
1/ Please try to disable all the third-party plugins (including cache plugins), that do not come bundled with XStore https://xstore.helpscoutdocs.com/article/36-included-plugins , clear the cache of the browser, and check then. Maybe one of the additional plugins is the reason for the problem.
2/ Please check how it works with the default WooCommerce theme – Storefront.
It is important to check if the problem persists with the default theme to find out if it comes from the theme or from something else.
Go to Appearance > Themes > install and activate the Storefront theme. Then test and let us know the result.
Widgets could be messed up after switching, so open the Appearance > Widgets tab before switching to be able to move the widgets to the correct area after switching back.
Regards
