Possible bug with Aes Uxorium trait

I am playing a Romani campaign, and one of my Type4 Client Rulers received the Aes Uxorium trait, which is a punishment for not being married. Because he isn't really a family member, he can't get married, right? So, assuming that's right, then these guys probably shouldn't be able to get the Aes Uxorium trait.

Heres a screenshot:

This bug is about as minor as it gets, but I just want to be sure someone did see this.

I reported it in the internal forum. I'm sure there are plenty of traits that should be disallowed for client rulers.

He I'd say. But then I did get a kick when one client ruler Spurius got to be a Quaestor.
