Some Reverse compatibility games not working

I recently bought three games at the same time for my Xbox Series S, metal gear rising (Xbox 360), far cry instincts (Xbox 360), and mortal shell (x/s). I got a receipt in my email confirming payment for all three games from both Microsoft and from PayPal.

When I try to launch metal gear or far cry, I am given the "do you own this game" error. I've tried reseting my Xbox, I've factory reset my Xbox. I tried uninstalling the games, but when I tried to reinstall, they weren't on my owned games list, and had to be bought again in the store.

The games show up on my accounts "purchase history" I am connected to the internet, and this Xbox is my home Xbox. I am able to play mortal shell and other games, including previously owned Xbox 360 games. These two games are the only ones I'm unable to play, any help is welcome.
