Menu customization problem

Hello! I’ve purchased your nice theme! (i can give you proof if needed)
Well, i’m trying to customize it, inserting a third menu voice.
Everything seemed ok, i’ve changed css and, for what i can understand about js, also scripts.js.
But the new-created menu content doesn’t behave as expected, it fits smaller than the other two original ones.

Here’s a demo: http://skeda.com/TEST/gris/
If you click on the new-created second voice (SERVIZI) you’ll notice that the content it’s smaller than it should be.
Where am i wrong?
Thanks
