Mega Menu Empty Column Headers Showing as '-' on Custom Post Type Pages

Hi,
Sorry for the late reply, I took a look at your page and for your “broken” menu an empty column header is being added which should not be there. If you could adjust your script’s logical to not add these would be best, otherwise to remove these try adding this script to the end of your functions.php file in Appearance > Editor:

function custom_script(){
  ?>
  <script>
(function($){
  $(document).ready(function(){
  	 $( '#menu-item-27209' ).each(function() {
  $( this ).find( '.mega_menu_title' ).remove(); 
});
$( '#menu-item-6186' ).each(function() {
  $( this ).find( '.mega_menu_title' ).remove(); 
});
$( '#menu-item-27235' ).each(function() {
  $( this ).find( '.mega_menu_title' ).remove(); 
});
});
})(jQuery);
</script>
<?php
}
add_action('wp_footer', 'custom_script');

I tried first to write this to use .RegExp() or nodeType == 3; to remove these, but I was not successful. It maybe helpful to add a class to these to target these better if you can though your script, but I don’t think this would improve my script that much for these three errors.
So while this is a “simple” solution I believe that it is also the most reliable for this situation.
After applying the script, please clear your browser cache and check.

Best regards,
Mike
