Embers of rage DLC question

[oliviahutch]

Hello,
I just bought all the DLC for Tome, but when I launch the Orc campaign every class group is locked except for Warrior and the new Steam classes from the DLC. I have over 200 hours in Tome and had every class and race unlocked before buying the DLC. Do I need to re-unlock all the classes for the Orc campaign, or are most of them simply not playable in that campaign?
