brahin As has been said before in another post, I really don't think you're going to find a copy of CCC with the level and depth of subtitle translation you're requesting on any streamer. LM can't "fix" anything with regard to the subtitles since the addition of subs is an automatic process. The torrent on the site now is the same quality you're going to find anywhere else. When a sub file of the quality you're looking for simply doesn't exist, there's nothing LM can do to provide anything better. Your best bet is going to be to search for a sub file that meets your specifications, and when and if you find that file, you can upload it to the player. I wish I had a better answer for you, but at this point, there simply isn't one.
You might have to consider a service like this one for the caliber of translation you're looking for: https://circletranslations.com/content/film-translation-services
