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

In an episode of "Jigoku Sensei Nube", actors Volcano Ota and Kiyohito Yoshikai are credited as "Ensemble Soul (English)" and "Ensemble Soul (German)." These are the original credits translated from Japanese, but I recently noticed that the actors were incorrectly moved to the "voice acting - dub" category.

How can I prevent this from happening?
