Why is it called this when official sources are referring to it as Attack on Titan Final Season... its not a part two if they refer to it as a continuation of the current season...

Unless it's a movie or only 1 episode that's how it goes based on our manual

well now even on official snk site it's being called part 2 :v
Because the fourth season isn't completed, it cuts around chapter 120-ish, while the manga goes up to 139. Those remaining 19 chapters are in the same arc; p1 cuts in the middle of it so its still final season because it continues the said arc, which is the final one
It's part 1 and 2 because they aren't released at the same time, but it still overall is only one season.
