Hello Juliana,
We suggest disabling all third-party plugins (including cache plugins) that do not come bundled with XStore (https://xstore.helpscoutdocs.com/article/36-included-plugins), clearing the cache of the browser, and then checking again. It is possible that one of the additional plugins is causing the issue.
If the issue persists, please keep all third-party plugins deactivated on your site and grant permission to debug your site, which includes deactivating all third-party plugins and on-site Customization, so that we can check and assist you accordingly.
Please note that you should take a complete backup of your site first.
Best Regards,
8Theme’s Team
