jQuery Zebra_Datepicker

jQuery Zebra_Datepicker

Hi,
 
I am using jQuery Zebra Datepicker plugin
 
I have got two dates FromDate and ToDate. The dates I have enabled are from 13/07/13 to 07/10/13.
I also pass in the array of disable dates in between these two dates i.e. 06/08/13 to 19/08/13.
This works fine.
 
          $('#FromDate').Zebra_DatePicker({
              format: 'd/m/Y',
            direction: [minDate, maxDate],
            disabled_dates: disabledDates,
            show_week_number: 'Wk',
            start_date: minDate,
            offset: [2, -2]
          });






 
BUT
 
When I go and select FromDate e.g. 13/07/13 it's gives me validation warning message
 
saying 'FromDate the date range 13/Jul/2013 to 07/Oct/2013 overlaps the range 06/Aug/2013 to 19/Aug/2013'
 
How Can I disable this message or check that it's not overlapping the dates.
