When the Mega Menu is activated it doesn't show submenus correctly. Instead of having a cursor which one can hover to see submenus, all the menus (and submenus) are displayed at the same time, in the same fashion, one after the other (without any of the distinguishing characteristics of a submenu).
This can be seen on our "About Us" menu, which currently shows all menus as if the same, while the backend/admin clearly shows there are submenus.
How does one get the Mega Menu to display the submenus properly?
