You can check and turn OFF the Options under XStore >> Theme Settings >> Speed Optimization. Try to check every option in that section one by one.
Otherwise, please 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 and also your permission to debug your site which includes deactivating all the third-party plugins and on-site Customization as well.
Note: Please take a complete backup of your site first, before going to disabling the plugins to avoid any inconvenience.
