Steps to reproduce:
1. Select 2 events using the checkboxes
2. Select "Delete" from the "Actions" menu
3. Uncheck the second event within the modal
4. Press "Delete"
All checked events from step 1 are deleted.
The unchecked event from step 3 is not deleted.
Workaround (if any):
The same occurs when applying a bulk tasks. The selection if the general tab is not respected.
