Netflix series just not in German?

For me the series like "white lines" are only in spanish and english, is set to german, but doesn't work. With another film that was Turkish, I had that too. That's not normal, is it? Does anyone know what to do?

You have to, if you are watching a episode at the bottom of the field with the small lines (audio and subtitles), you can set the language. If that doesn't work, the series are not well known and therefore have not been translated or synchronized

Nothing of these series is only available in these languages
