Hello, Ritik Kumar,
We suggest that you first try disabling all third-party plugins (including cache plugins) that are not bundled with XStore. You can refer to the following link for a list of included plugins: https://www.8theme.com/documentation/xstore/plugins/included-plugins/ . Additionally, please clear the cache of your browser and check again. It is possible that one of the additional plugins adds the mentioned text.
Kind Regards,
8theme team
