DLC Problems

So I just recently started playing Halo 3 again and it says I’m still missing DLC. I have downloaded Mythic 1 &2, Cold Storage , Legendary, and Heroic. Is there something I’m missing? I’ve looked through the marketplace at least 10 times!

Thats all of them. Try re-downloading them. If that still doesnt work then transfer the license to that console and re-download. It should work then.
