Confused about Japan Update files

I have been playing 2024 since release and it’s the only MSFS I have installed.

That being said, I downloaded the latest Sim update 4 and I had a few updates to planes, scenery, in my library on the in game store. I updated everything except there was one last update and it was for a ‘Japan World update’ but it said it’s the 2020 one? It was disabled when I saw it but still needed an update. Should I have kept it disabled since it’s 2020?
