Experience same problems…
Add a new topic : with a repeating event when you click on it in the calendar,
the post event show that the vent start at the date you have clicked, and end at the date you have click plus the duration of the vent.
SAmple :
if the repeating event began on april 12th and finish on april 19th
if you click on this event in the calendar ot the 15th of april,
the event page said : begin april 15th to april 22th..
Sorry for my english !!
