Completion Stamps Missing?

I started up MCC the other day to play some H4 Spartan Ops and the stamps saying I beat Legendary solo and co-op are missing. I’ve also noticed all my audio files from ODST are not saved and I have to refind them. Has anyone else experienced this?

The audio files in odst reset I believe from one playthrough to the next (you start a plahthrough or reset checkpoints from title screen) as for the Spartan ops I’m not sure, but if you post this in Halo support forums it may get more attention, and or better answers to solve the issue.
