It's in the two areas.
Movie: https://www.themoviedb.org/movie/433672-mannen-van-dokter-anne IMDB ID tt6313102
TV Show: https://www.themoviedb.org/tv/69965-de-mannen-van-dokter-anne

https://www.imdb.com/title/tt6313102/

I would delete the movie entry

Add 3 cast
Move IMDB ID... Ops!
Find another https://www.themoviedb.org/tv/69483-mannen-van-dokter-anne

Now, we have
OLD 0 https://www.themoviedb.org/tv/69483-mannen-van-dokter-anne IMDB ID tt6313102
new 1 https://www.themoviedb.org/tv/69965-de-mannen-van-dokter-anne
new 2 https://www.themoviedb.org/movie/433672-mannen-van-dokter-anne imdb id tt6313102

Same IMDB ID ! ?
Is it not checked between TV and movie?

I suppose OLD 0 should stay.

I have added all information to the oldest one (OLD 0) so NEW 1 en 2 can be deleted

I have indeed adjusted the episodes description because 1 and 3 were both more general serie descriptions and 5 and 6 were actually the same description, one was only a lot longer then te other.

So I think it should be OK now

I will leave here the link of the 2 images of the new 1, if it is of your interest to put in OLD 0.
