subtitles not found on some YouTube videos

[az0]

I can see the subtitles for this video on YouTube and download them using DownSub, but the latest youtube-dl does not download the subtitles. I have noticed this is a problem for half the videos in a particular series from the same publisher.

What is the purpose of your issue?
