Not receiving credit for Hard Mode levels

I have completed the Reign of Chaos campaigns on Hard Mode when I realized that I did not receive credit for the last two levels of the Undead Campaign. I went back and beat them again on hard just to make sure, and still did not receive credit. It is only those two levels, I put it in a ticket and was told to put in a report here. What is the fix for this?

Did you start those two levels from a save point, or restart them? You won’t get credit starting a level from a save point.

No, the first time I did not, the replay though I did.
