Renaming provinces in-game - not working

[Fresh]

I posted this on the bug forum with no reply, so I figured I will put this here as well.

Renaming provinces in-game seems not to be working (it worked in the demo). Does anyone know if it is a bug or was it disabled on purpose?

From what I can tell, you have to be an independent ruler in order to be able to rename provinces in your realm. I had to load as the Holy Roman Emperor to rename my Pommeranian provinces to their proper Slavic names as Bohemia.

That might be right, since I only tried renaming as King of Poland in the demo. Now I am a duke under a king and it is not working.
Thank's!
