[Inf-IT DAVcl] Completed tasks not displaying Caldavzap

Updated 8/5/2013 Completed tasks do not display. Marking items complete using Lightning. Actually sounds like a Lightning issue to me. If I mark it complete by opening the task and setting it complete in the dialog box it will not show up at all in caldavzap. In order to get completed tasks to show up I must set to 100% complete, close and save, then mark as complete.
