Is the year period for the TV Series correct?

The TV Series https://www.imdb.com/title/tt13920900/ year period is indicated 2021-2024. In fact 1st episode was released in 2023 and in 2024 the TV Series was ended. There was the pilot episode premiered at some festivals in 2021 and 2022, but is it the right reason for indicating the title as "2021-2024" while the entire series was released at 2023-2024 ? The pilot presented at those festivals was more of a working version, made before real premiere.
