So whenever you import a YouTube video the subtitles tend to have odd line breaks throughout. That doesn’t bother me. Unfortunately, those line breaks cause problems if you’re trying to select a phrase that begins on one line and ends on another. Basically, you can’t select and highlight text across from one line to another because of those odd line breaks.
Yes, that can be a problem and it’s related to uploaded subtitles format.
What you can do in those cases is to edit a lesson and re-arrange paragraphs manually.
