Hello, Shirley Djaka,
Thank you for contacting us and for using XStore.
Could you please check how it works when Advanced Layout is disabled in Theme Options > WooCommerce > Cart/Checkout Layout?
Let us know the result.
Please note that we do not give a guarantee for full theme compatibility with all existing 3rd party plugins. Sometimes, not always, you need additionally customize the theme or plugin to make them work together. Unfortunately, it’s not possible for the author to make the theme compatible with all the existing plugins and additional customization is outside the scope of our basic support.
Kind Regards,
8theme team
