Problem with Menu on mobile devices

I have just gone live with me website using the Figero Pro theme and just discovered that the navigation menu on the home page doesn't work on any of the mobile devices I've tested. I see a box that says "Pages Navigation Menu" with a down arrow on it, but it doesn't let me navigate. Is there something I can do to fix this fairly quickly? i just went live and I don't want to have to go back to the old site.
