Getting an error message in customize screen

Hi guys, This error: Warning: Creating default object from empty value in /home/content/p3pnexwpnas08_data03/28/2754728/html/wp-content/themes/catch-responsive-pro/inc/customizer-includes/catchresponsive-customizer.php on line 110 pops up when I go into the customize appearance area. I have a menu item that uses "void" as it doesn't link to any pages (I wanted to have a parent menu item for a couple of child pages). Could that be causing it?
