Date year range has no effect on the results

Sorry, I did not recognize that I forgot the attachment.

Here the export of the view:

Thanks.

Is there anybody there who can give me a hint how to solve this problem. Otherwise I must delete a lot of events.
It would be very nice to get this view work as intended.

Thanks.
