Halo 1 Anniversary Campaign error

Hi guys,

I recently played Halo 1 anniversary campaign co-op on legendary on the master chief collection.
I successfully beat the first three levels, and I was awarded the achievements for doing so.
But when I see which levels I have beaten on the mission select menu, it says I have only completed level 1 and 3.
The game thinks I have not completed level 2, even though I have, and I was awarded the achievement.

Will I have to beat level 2 on legendary again? Or can this be fixed.

Try restarting your Xbox and trying again. When I played BF4 this happened to me. The game didn’t even read that I beat the missions.
