Extra Details: I just saw the movie and did not spot actress Zita Hanrot, she was also not mentioned on the credits of the movie and is not credited on Imdb either...

Feel free to remove her from the cast if she hasn't been removed already.

so I think this is a mistake in the cast listed here. And there might be other mistakes too?

That's bound to happen when the cast and crew are added before release, based on what has been added to IMDb or based on reports from unconfirmed sources.
