I can tell you how to remove it but I would have to look at your navbar template. If you put it in the way I posted it in the first post then then you would go into the Navbar template and remove the lines between. But I can not guarantee this without looking at it.
If you did as the direction I posted and left the comment tags in the code then you would remove the lines between these two lines including these two lines:
<!-- nav buttons bar -->
<!-- / NAVBAR POPUP MENUS -->
