Additional info

Was able to delete it after the date of affected calender entry was updated

@paramazo

Is this issue still happening? Can you post the event causing the issue?

[paramazo]

We are not using this feature anymore, so i dont know if this is still an issue.

[SebastianKrupinski]

@paramazo I will close the ticket then, you can reopen it in the future, if the problem returns.
