On some TVShows there is a different "number_of_episodes" in the TVShow facts, if the Information is requested by "/tv/{id}".

On these TVShows the number of episodes is mostly one less than the "count" of all episodes of all seasons.

For example there a these TVShows i found: Heroes Reborn: https://www.themoviedb.org/tv/60858-heroes-reborn 1 Season with 1 Episode but in the API-Request there are 0 Episodes for the "number_of_episodes".

Gotham: https://www.themoviedb.org/tv/60708-gotham 1 Season with 22 Episodes but in the API-Request there are 21 Episodes for the "number_of_episodes".

I know the difference between requesting the "number_of_episodes" via the "/tv/{id}" call and calculate the number of Episodes via call the "/tv/{id}/season/{season_number}" and count the "episodes" array.

But at the end, there have to be the same result or not?

Can someone explain me whats wrong or whats my problem here?
