Facebook-muting PTE videos' music

[goddi]

Greetings,

I have many dozens of PTE shows on my Facebook site. I happened to browse through them yesterday and I noted that many dozens of them have the "Your video is partially muted because it may contain music that belongs to someone else" notice.

I have been careful to use non-copyrighted music. However, I noticed many dozens of shows had this notice but the music source is non-copyrighted music. I was able to 'Restore Audio' and remove the notice for all of them.

I am wondering if anyone else has noticed this out-of-the-blue muting of videos in Facebook. They originally were posted without this notice and suddenly I found, going back many years, the videos received this muting of the videos when they did not originally receive it.
