service record "legacy" error

ok, so the issue is when i go to my service record and then to the legacy sub section where it shows your past halo campaign difficulty completion. I have beaten both halo 3 and ODST on legendary and have the achievements for both, but it show that i have only completed ODST on normal when i go to the service record.

i know this isn’t a serious issue, but its important to me.

For it to register as done on legendary, they all need to be done on either co-op or solo, not a mix of both.

I had your exact problem too.

I solved it when I buyed my new console.

I would suggest you to delete waypoint, clear hdd cache and re-download waypoint letting it re-scanning your profile.

hmm, im pretty sure i did it all co-op but not 100%, but thanks for the help
