Year range Hey Arnold!

Currently, the year range for Hey Arnold! is listed as 1996-2022: https://www.imdb.com/title/tt0115200/reference/ 

As you can see via the episodes, the series ran from 1996-2004. 

Screenrant also says this: https://screenrant.com/db/tv-show/hey-arnold/articles/1/

The same goes for themoviedb.org: https://www.themoviedb.org/tv/537-hey-arnold/season/5/episode/42 

Can a staffer look into what happened here and correct the year range please?
