The tracks loading logic should he redone in my opinion, it's pretty jank, sometimes duplicating or missing some tracks in the ui.

Ok, found the problem. I was using "jp" for lang instead of "ja," which caused the function to throw an exception.
Also, it seems that it doesn't work well when the track has a two-letter code lang.
For example, given a track "Full (eng)", it will work with lang "en" and "eng", but with the track "Full (en)" neither work.

Also, I think it would be better not to use the app's language by default if no lang is set. Sometimes I change the videos' default track and now it chooses a different one. If people need it they can always add their language to lang.
