The mod was originally made having the Main Campaign and the old Imperial Splendor mod, the IS guys also incorporated to their new RotR campaign. It wasn't tested in any of the expansions, you should probably uncheck the mod whilst playing them.
If you want to fix this issue yourself, my bet would be in excluding the traits to the RtI factions. IIRC you cannot make a trait dependent or triggered by the existence of a building or tech, this trigger is in the .lua files, but I think (like 90% of triggers) it doesn't work.
