TV Shows : Planet Earth (2006) cannot be imported into library.

I use: http://www.themoviedb.org as my TV Shows source (I think it is better than the TVdb)

On http://www.themoviedb.org there are 2 TV Shows:

Planet Earth (2006) (11 episodes)
https://www.themoviedb.org/tv/1044-plane...uage=en-US

Planet Earth: The Future (2006)  (3 episodes)
https://www.themoviedb.org/tv/20618-plan...uage=en-US

I want to import Planet Earth (2006).  BUT no matter what I change the file name/folder name, I always get  Planet Earth: The Future (2006)  (3 episodes)

What should I do? What's the right way to name it?

Here is an example I using: (NOT working)
Planet Earth/Season1/From.Pole.to.Pole.2006.S01E01.mkv
