Deleting an event of a recurrence deletes all recurrence

If you delete the first event of a recurrence and choose to delete only that one, the entire recurrence is always deleted

Steps to reproduce

• create a new recurrence: event every day from 4 to 5 pm for 5 occurrences
• right click on the first occurrence and delete
• leave the default choice: this event

Expected behaviour

• the single event is eliminated and the chain is broken

Actual behaviour

• all recurrence is deleted
