How can the transfer of language-linked credits be prevented?

The thing is, that happened a few days after the credits were added. It seemed automatic, since the names included "(english)" and "(german)".

@DuraNext​ The problem here is the format of the character name — the best way to represent this in a character name, if it is not a dubbing credit, would be “Ensemble Soul: English” — wrapping the language in () makes it look like a legacy credit from before the voice dubbing category launched and is therefore liable to be converted to voice dubbing.  

Hope this helps. 

Thanks for the reply. I used parentheses because the original credit used them too, but in this case, I'll change it a bit to avoid this kind of issue.
