Hey there,
Regretfully, this particular customization request is outside the scope of our support as this is not related to an issue with the theme and instead has to do with your customization of it. As such, you will need to investigate this particular issue on your own or seek help from a developer should you not feel comfortable making these changes yourself.
Also see https://community.theme.co/kb/integrated-plugins-ubermenu/ for UberMenu usage instructions and X integration.
Thank you for your understanding.
