I uninstalled a game from Game Pass, but it's still taking up storage space.

I was just downloading some game and testing them out and uninstalling them as I went along. Everything seemed fine, but when I uninstalled Shadow of War (which has a rather large install size), it doesn't show up on the Game Pass app, indicating it's been uninstalled, but my storage didn't change at all. Is there any way to sort this out?

*edit* Got it sorted out. Was stowed away in the temporary files for game delivery optimization or something to that extent. I'll have to keep that in mind going forward.
