Thank you very much for your help, Claude. I will have in mind your advices.
Hi Andrés,
Thanks for your message yesterday where you explained that the issue repeated itself in the "metadata: geo" subtitles. I replied explaining how you could squat another metadata language track to get a new translation interface showing the original English subtitles.
However, a closer look at the English subtitles makes me think it would be better to wait until they are finished, as the subtitler is not following the chronological order. And this might perhaps contribute to the issue with the translation interface.
Just an hypothesis, though. If you want to continue right now all the same, I'm ready to go on helping you squat as many inexisting "metadata" and duplicate languages as needed :)
