title: How to edit Title in Fullcalendar
body: <p>I'm trying to use the fullcalendar library in ServiceNow and everything seems to be working fine, but there's something weird going on with the Title:</p>
  
  <p><a href="https://i.stack.imgur.com/Y7MSE.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Y7MSE.png" alt="enter image description here"></a></p>
  
  <p>Is there a way to get rid the undefinedundefined by making changes to the Title object?  My current code is pretty simple:</p>
  
  <pre><code>$('#calendar').fullCalendar({
      header: {
          left: 'today prev,next',
          center: 'title',
          right: 'month,agendaWeek,agendaDay'
      }
  })
  </code></pre>
