Could not add Episode Assets

I have a new installation of podlove publisher and i try to add the correct settings.

When i try to ad new “episode assets” i become a problem.

It doesn`t matter if i push “Änderungen übernehmen” or “Save the changes and continue editing”.
In both cases word press shows me the 404-page of my page with the URL:

Is this a problem with my setting or a bug?

Please update to 2.3.17. Bug has been fixed.
