• LibreTube Subtitles: None, English, English, (some japanese characters i cant read)
• Piped Subtitles: English, Off
• Youtube Subtitles: Off, English, English - Neobrane, Japanese (auto-generated).

Youtubes subtitles are much more descriptive and useful.

Imo, this is a bug. How come the caption names are not the same as youtubes by default?

I suspect that in both cases it's a problem with the the app, not NewPipe extractor.

For Piped it's definitely an issue on their end (I checked their code), they don't tell shaka-player to use the labels, so it defaults to displaying the name of the language and as those tracks are both English, Piped only displays one of them.

I suspect it is a similar problem with LibreTube, that they display the language of the track instead of the label.

NewPipeExtractor extracts the labels, those two apps just don't use them, this is not a NewPipeExtractor issue.
