repeating events

How can you modify an event without recreating the recurring series?

I use JEM 4.4.2 and Joomla 5.4.5

In JEM 4.4.2, when you create a recurring event series, child events can be modified individually (title, description, etc.) without breaking the series. However, modifying the first event (root) in the series replicates those changes to all events in the series.
