"When I play as rome I have a faction member from another empire in my family, does anyone know why, or how to get rid of it? (I can't kill him, can't perform any actions with him, but he is a general in my army, which I can use on the field."

the general is from the seleucid empire and son of romes king. i have run the game with out anyother mods but still the same result. also i looked through the mod files and i don't know how to fix it. is this something that will be fixed?
