Not sure if it's a bug. The main character have a random initial trait, and get others like the servants (like pervert, as an example). The ways to see the traits are:
Through "relatives" window
Through "remove trait" on laboratory
Using potion of clarity on the main character.
This looks like a bug because no mention on acquiring the new traits are made, nor do I can see them through "ispect" section.
