Halo 4 campaign on legendary, no armor

Didnt have cable due to hurricane sandy so i beat halo 4 offline. When i reconnected it did not register to halo waypoint or my service record that i beat the game on legendary and i have no intentions of attempting to beat it again. btw i have the achievements to prove i beat it. help.

I have the same problem. I finished the campaign on legendary but I unlocked the armor of chief

I finished the campaign on legendary, got the armor… But my campaign progress still says my highest difficulty completed is normal :frowning:
