Lone Wolf Achievement Glitched

I beat the game on Legendary and the achievement is stuck on 86%. It registers in game and on here that I beat all missions on Legendary and I’ve tried to replay some missions… Anyone have a fix for this?

According to this, you have several missions that don’t have any time or info registered. I’d go back and replay those missions.

no dice. replayed the game; the percentage did go up though
