error "Audio file size"

I imported subtitles from
Login - LingQ
when I go to edit the lesson I get this error
where does this audio file come from?
it says it’s 15:18 minutes. It can’t be the audio from the show because the show is over 1hour long.

I assume LingQ imported grabbed some audio that was available on the page you imported the subtitles from. You can just select “Remove uploaded audio” option, then save a lesson and it will be deleted.
