Hi Mark,
in CalDavZAP you will see completed tasks only for the selected month (in the small calendar above your todo entries) or later. Completed tasks before the selected month are hidden to prevent displaying data from past years (you can have thousands of completed todos from past).
If you think that your bug is not related to the functionality described above, then send us the problematic ics file (with the completed task which is invisible in 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.
