I read in this in the comments of the offline campaigns co-op run: "Main Campaigns refers to the campaigns that are considered "main" in the original L4D2".
L4D2's Main Campaigns category doesn't have The Passing because The Passing released after as DLC. I assume the intention is to make this the same as the normal L4D2 boards, no?
edit: someone else got a response in DMs, so nevermind
I made the mistake earlier of adding The Passing to the list of maps required for Main Campaigns and I actually removed it an hour ago before you posted this. It's not supposed to be part of any Main Campaign runs.
After discussion among the mods, we've reached an agreement to make a couple of rule changes to the boards. These changes will go into effect at the posting of this news post, so please pay attention to the changes below.
- The callvote command will be banned in all categories from now on
