#679 Deleted events (one of recurring series) still appearing in calendar?

[Johan]

We are using the calendar on a web site for a class schedule, on one of my customers web sites (http://savestores.com).
He enters his events in Zimbra. My web server downloads the .ics files from Zimbra daily.
He created recurring events, then later went into zimbra and deleted one of the occurrences of the events, on July 23rd. The calendar still shows the events on that day?
I downloaded the .ics file to my machine, imported it into my Zimbra calendar, and the events are not there on that day. I attach the calendar file. July 23rd should be completely blank.
We really like the features of this calendar. Its just this is somewhat of a show stopper for my customer.
