I have removed all of the events that have this issue and recreated them. All future instances now have the correct date.
I guess that the case can be closed, but it is concerning that we don’t know why this happened.
Thanks for the reply.
I don’t think It’s an issue with time zones.
The original event is for 120 minutes 10 to 12. The recurring events change to an 8 am to 5 pm event.
I would understand if the event had changed to a different time but for the same duration. But the duration has completely changed also.
Hope you can get to the bottom of this.
Thank you.
