Sorry bad english

I will explain: I wanted to play like a legendary Lord (Faction Leader) with a Helmet (no face) and put my own name in this Legendary Lord and then begin my own Empire.

But for some unknown reason the unique legendary lord with a Helmet hiding his face that I can rename is Lupio Suncryer from Estalia.

Exist some otehrs Legendary Lords (Faction leader) with Helmet on Bretonnia races that is impossible to rename.

Do you can ebable the option to rename others faction leaders ? I wanted to try to play with someone else besides Estalia faction.
