two menus on mobile version

Hello,

I have downloaded the max mega menu, and I am very happy how my site looks when visiting from a computer.
But when I access the site from my iphone, under the title comes now to menus, and only one of them works. Anyone knows how to get rid of this problem?

my temporary site is:
181.224.130.249/~andersfa/
