I'm having the same problem as my colleague when adding an event:
adding a repeating event on monday and it shows the appointment on tuesday. correct time and nicely repeating. In edit event it shows monday, so entry is correct.
Now some more (new) info:
in day view it doesn't show at all and in Month view they show correctly on Monday!
Now when I add a new event on the same time and day, it shows the first event correctly, and this new event on Tuesday. So it kinda pushes the first event 'in place'. BUT they both take only half the space in the agenda, like they are on the same day and need to share the space for that timeslot! The event on Tuesday ( wrong day) is half covered by an appointment that is already on Tuesday, so it doesn't behave like it should be on Tuesday (which is correct, it should be on Monday...)
In the screenshot you see IN: NG&FV which is the first event, and on tuesday 'test', bot scheduled for monday 9:30-10:30. Now when I delete 'test', IN:NG&FV moves to tuesday, takes full width and also half covered by the event of 9:00.
Hope this helps some more.
