Add the following empty div where you want to display current menu label
<div class="menu-label-container"></div>
and add the following script in footer of the page.
jQuery(document).ready(function(){
if(jQuery('#nav li.current-menu-item a').html())
jQuery('.menu-label-container').html(jQuery('#nav li.current-menu-item a').html());
});
Tell me whether this solution is working for you or i will find another solution.
