Some events show wrong time in Event Editor

I have encountered an annoying issue with incorrect times being shown for some events in the Repetition Pattern section of the Event Editor.

For example, the event Yoga and Sports at Pool N is a repeating event that occurs on 15 October 2022, 5 November 2022, and 4 March 2023 from 18:00-20:00 on each date. The event appears correctly in the calendar for each date. However, in the Repetition Pattern section of the Event Editor, the time shown for the 4 March 2023 event is 19:00-21:00 (but the times for the 15 October 2022 and 5 November 2022 events are shown correctly as 18:00-20:00).

In attempt to resolve this, I’ve deleted the March 4 instance, updated the event, closed the Event Editor, re-opened the Event Editor, and recreated the March 4 instance. However, the time once again shows incorrectly in the Event Editor.

I wonder if this has anything to do with DST (although DST started a week later).

Here are a couple of screen shots showing the event in the calendar and in the Event Editor.
