Calendar not working correctly for recuring appoints that span over midnigjht

calendar appt:
7pm Fri-7am Sat, recurrs weekly every 2 weeks on Fri, Sat & Sun.

Problem: The calendar shows the Sun 1 week later!!

eg. 4th Oct (Fri), 5th Oct (Sat) & 13th Oct (Sun) (should be 6th Oct)

I will need one or two of those faulty events exported into .ics (right click on event - save as) and sent to [email protected] with this topic’s URL.

Also what version of eM Client do you use (help - about)

regards
Jan
