Auto Enter Calc for zulu_UUID in Events Table

I'm running into issues with publishing my events, only a small fraction of them appear in iCal. I've noticed that the only events that *do* appear are the ones that have a value in the zulu_UUID. I'm assuming that this gets populated during the "Publish Calendar" step. I have checked and rechecked my ZuluCalendarList record and experimented with filtering (which does seem to be working nicely) but can't figure out why events that satisfy my filter criteria aren't appearing on my calendar in iCal.
The documentation on this page:
http://www.seedcode.com/pmwiki/pmwiki.p ... ntegration
refers to an auto enter calculation for the zulu_UUID field. I've checked this field in your sample file and see that it's configured to Auto-enter data = "".
Is this correct? Is this auto enter setting even relevant to my issue?
