Steps to reproduce:
1. Open event details or series details
2. Set "Title" to empty string
3. Hit "Enter"
The Admin UI indicates that "Title" has been updated. It does not update it, however, as title is a required field that cannot be set to an empty string (which is correct).
The Admin UI should provide user feedback, i.e. indicate for required fields that the empty value is not valid and will not be saved
Workaround (if any):
