Mobile(?) drop down goto menu appearing after them update

I have the avada theme on my website http://www.dermotmurphy.com and I just updated the theme to the latest versions.

Now a storage goto drop down menu is appearing along with the top navigation ( i notice that the page loads properly and then after a second the menu fonts change and this little drop down box appears)

Any ideas why and how to get third of it?

Please see attached screenshot.

Thanks in advance.
