Odd things happening with the Club Calendar feature

Hi team

About a year ago we had some trouble with the club calendar function "stepping" recurring events, such as Club Meetings, by a day so that a club that meets on Thursday, for example, suddenly showed as meeting on Friday. This appeared to have something to do with the change to and from summertime here in New Zealand.

I have just noticed that the problem seems to have reared its ugly head again, only this time with a variation!
For some clubs the recurring calendar item suddenly stops as in the example screenshot for club 4714198. This has also happened for club 8649. Both these clubs meet weekly.
Club 4527937, which meets fortnightly, on the other hand, shows as meeting on Thursday in September but in October we are apparently meeting on Friday.

I look forward to hearing what you think. Please reach out if you need further information

Many thanks

does the date/time appear correct when you select NZ as the time zone?

Hi Brian

Yes, date & time appear correct. We are currently UTC + 1300

open the agendas of the dates in question and save them.
Do the calendar entries show correctly?
