Zoho CRM is not syncing all of my events to Zoho Mobile.

Zoho CRM is not syncing all of my events to Zoho Mobile.

All of my appointments (EVENTS) are saved in my zoho crm online.  When I sync that with mobile, if I have a repeating appointment say every thursday at 9 am it changes the date in mobile from every thursday starting in 2013 to every thursday starting sometime in 2014.  It also is leaving out individual appointments that are not recurring events just one time appointments.  My sales people can not see their appointments now.
