What is meant by “creative differences” between a director and a studio?

I’ve never really understood how a director has that much input when they’re directing a script that’s already written (in this scenario let’s assume they haven’t got a writing credit)

Like for example the new Doctor Strange has lost its director because he wanted to make a the franchises first horror film, but how can you make a film that isn’t a horror film on paper... horror?

It’s just something that’s always confused me and I’d like an answer right now!
