duplicate entries? movies as seasons?

https://www.imdb.com/title/tt14134334/episodes/?season=1

https://www.imdb.com/title/tt14134334/episodes/?season=3

https://www.imdb.com/title/tt18364006/?ref_=ttep_rvi_tt_t_2

so the first film was retroactively put as the first season of the later show

the original entry with all its ratings and information was deleted

and then another film is duplicated as the third season of the show

which way it should be?
