Instrument names in German version

I guess it is generally better to use an old thread than to start a new one. A question on this.

I am not on the german version, just keeping language in preferences set to default. In a score with many players already present, I decide to split the Basso line into Violoncello and Contrabbasso. Violoncello already exists, but Contrabbasso has to be created. I set the instrument name language to italian and create the player: Kontrabass.

According to what you are saying, this new player should get the italian name, shouldn’t it? Am I missing some vital step here?

Thanks
