As I have answer you in the API support forum, it appears that the TV show https://www.themoviedb.org/tv/99358 is a duplicate of the second season of the TV show https://www.themoviedb.org/tv/64197-nirvana-in-fire . This explain why the data returned are the same.

As I don't know these specific TV shows, I don't know if it should be 2 separate shows or 2 seasons of the same show, we will have to wait for the look of another moderator.

“琅琊榜”-“nirvana-in-fire”is the first seasons，“琅琊榜之风起长林”-“Nirvana in Fire Ⅱ” is the second seasons.Need administrators to delete duplicates.

It can be understood that these are two different TV dramas. By the way, in most cases in China, the performers of multi season TV dramas are different.
