 * While the plugin is active I get this javascript error in my Chrome console and
   it breaks other functions of my website such as the mobile menu. If I switch 
   to legacy styles the errors go away and everything functions properly.
 * Uncaught TypeError: Cannot read property ‘indeterminate’ of null
