It appears that leaders that I recruit are all getting the "Traditional" trait added to them after I recruit them.  The first screen snapshot (on the left) shows what the leader named "Puddle Woe" looked like before I recruited him and the second screen snashot (on the right) shows what he looked like after I recruited him.

I have 5 unassigned leaders and they all have the "Traditional" trait.  In fact, all of my leaders, whether they are unassigned, Ministers, Governors, Diplomats, Commanders, or in a Faction. have the "Traditional" trait.

I looked at all of the Cultural Traits in the "Traditionalism" ideology and I do not see any trait that would grant that leader trait.

Is there something I am missing?
