Halo 2 and 3 installed but not playable in game

I downloaded the master chief collection. It downloaded the rest of the collection after it install on the Microsoft store, because it has to download on the Microsoft store first then the game. Everytime I go to the multiplayer or campaign it doesn’t let me play halo 2 or halo 3 and I paid for 2 because I wanted to play it and keep it.{I have the game pass} I’ve made sure it’s in the right Storage, I’ve redownloaded it numerous amounts of times and it’s still not working. NEED HELP!
