Hello, @ubi1907,
Try to disable all the third-party plugins (including cache plugins), that does 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 a reason for the problem. If the issue still persists then please keep the plugins disabled and let us know I will debug in deep to find the cause of the issue.
Note: Please take a complete backup of your site first before going to disabling the plugins.
Regards 8Themes Team.
