Create events with multiple instances.
Select multiple individual instances of these recurring events
Select to delete the selected events

Result:
The complete events are deleted, not only the selected instances.

This behavior is not what I would expect, as the user has selected multiple specific items I would expect the action he wants to perform should be applied to specifically these events. Another possibility would be to add an intermediate dialog just as is done when applying an action to a single instance (The text could be: 'The items you are editing are repeating items. Do you want to edit all occurences of them or only these single instances?' for example)
