I have just tested it at my end on my test site and it is working perfectly fine for me, it seems the issue is on your site only.
We suggest disabling all third-party plugins (including cache plugins) that are not included with XStore (https://xstore.helpscoutdocs.com/article/36-included-plugins), clearing the browser cache, 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 customizations, so that we can investigate and provide assistance.
And Please also share your site WP Admin URL and Credentials in the private content area of this topic.
Please note that you should take a complete backup of your site before proceeding.
