Happened twice to me aswell just recently. Got confused and digged a bit through the Web..

Solution = when you are on your VoD Page, click the 3 dots and then protest against the claim.(might be named different but u get what i mean)

You want to fill out what is asked for and maybe an hour later max u get an email from twitch with the info that you won and gg, your audio is now like it should be.

Hope this helps whoever runs into this bs <3
