Tomb Raider I-III Maturity Rating Issue

I noticed that Tomb Raider I-III Remastered Starring Lara Croft is listed on IMDb as Rated M for Maturity, but on esrb.org it is listed as Rated T for Teen. So, I tried to contribute and update the rating so that it matches its actual rating. But, it still lists it as Rated M. So, I ask: Why is the rating still M when its official rating is T? Why don’t they update the rating when it’s incorrect, just like they did with Stranger Things Season 5?
