Things like the mislabeling were Yamah's researchers fault. they basically are saying in the developers notes, we screwed up and everyone has been copying our screw up since. Since nobody bothered to update the script, for example, and way Vocaloids were done for English resulted in many mistakes being easily made.

Zero-G, PowerFX, Crypton, Internet co and Nana's developers were basically innocents who didn't realise.

Even if you read the notes alone, part of the problem their team faced was half the team were Japanese, hence why they hired two English teachers to even out the squad. When they went to vote on sounds, the Japanese peeps didn't know what was wrong, since the team was more then half Japanese this meant the English speakers got out voted all the time.

so basically, this presents the problem that any English studio was facing pre-Diva.
