Backwards compatible store page.

The issue comes directly from the backwards compatible section of the Xbox One store page.

Hi Mechro,

Thanks for your post. To troubleshoot this issue, I'd recommend performing a
Soft Factory Reset. A soft factory reset will correct any software issues that could prevent the console from showing these items on the store.

I hope this helps, please keep us updated.

Hi Mechro,

Thanks for the reply to keep us updated. The Microsoft Store is separate from the 360 Marketplace when it comes to purchases for the console, regardless of whether you are looking at it from a PC or console. Via the Microsoft Store itself, there is no delineation
for Backwards compatible games listed or a section for that; however, at Xbox.com there is, and when a game is selected from that list, will take you over to the 360 Marketplace for details and purchase information. It does the same when selecting a 360 game
from the MS store on the console as well.

Is the page that you are specifically referring to the Backward Compatible Game Library list from Xbox.com? If not, then please reply and provide
a link to the page that you are experiencing the trouble with please.

Thanks again and we will wait for your reply.

This issue has persisted for around 3 or so months and this has not fixed the issue.

Hi there,

Thanks for reaching out to us in the forums with this issue. Sorry to hear that you're having difficulty with the Microsoft Store under the Backward
Compatible Game Library, which does contain the games you listed. If you are searching the MS Store via a PC, you may wish to clear the cache/cookies from your web browser and try again. If you're searching via your console, you may wish to

perform a physical power cycle to your console and then attempt to locate the backwards compatible library again.

1. Turn off the Xbox One console by pressing the Xbox button
   on the front of the console for about 10 seconds until it shuts down completely.
   
2. Unplug the console's power cable. Wait 10 seconds.
   Important Be sure to wait 10 seconds. This step resets the power supply.
   
3. Plug the console power cable back in.
4. Press the Xbox button
   on your console to turn on the Xbox One.

I hope this helps out and happy gaming!
