The “show P2P links” option should only be used if you’ve set yourself up with a VPN, since that’s just straight streaming torrent files. I personally never use it, since it’s usually slow and laggy, and will look for the media on another source if necessary.
For the subtitles, there’s should def be other options to try in the same language, but sometimes for more obscure media you’ll have to adjust the timing on what subtitles are available.
