Forum:Playthrough 2.5 Help

I've completed the main story of playthrough 2, and I'm in "Playthrough 2.5", and everything in the main content is matching my level. Everything in Zombie Island DLC is also matching my level. However, the enemies in the Knoxx DLC are NOT, they are their regular levels. I haven't checked the other two DLCs. What am I doing wrong?

The only thing coming to mind is that I completed Playthrough One's Zombie Island DLC, but not Knoxx's. Is that it?
