He's referring to the fact that the Level 6 and 7 achievements have not been unlocked in his campaign completion efforts.
OS: My suggestion for this is that you didn't complete it on a difficulty of Normal or higher. Hence, you haven't unlocked the "Campaign complete" achievements, either. That's about the only reason I can think of for your problem.
