Two Menu Toggle Buttons on Mobile View

Hi guys

Hopefully this is an easy fix, but I cannot find the correct CSS to sort it.

I’m using Max Mega Menu and when I view my site in mobile view, it’s giving me two toggle buttons. I guess it is trying to show me the original menu, in addition to the Max Mega one. Is there any CSS I could add to remove the themes toggle button from mobile view?

Thanks in advance!
