MCC Total Missions Completed not incrementing

Hi all,

The counter for MCC “Total Missions Completed” regarding my Xbox gamertag’s profile achievements is stuck from long time ago on 296. Not a big deal and I already have “The long haul” achievement which is completing 500. But I’m curious about the reason why this counter is not being incremented anymore, doesn’t matter if I complete campaign missions or MP games.

I’ve searched the internet with no success. Compared to friends, it is working for them.

Anyone here with same issue or any idea on what’s going on? Thank you.
