Subtitles in VLC are wrong

I have an .MKV file and the subtitles are incorrect

I tried with different encondings as this answer states, but I with no luck. The subtitles are embedded inside the file so I can't open them in notepad++ to verify if they are ok..

What else can I do ? Since there are many files, and they all have the same issue, I don't think there was a problem when downloading them.

This is on Windows 7, VLC Version 2.2.1

Thanks in Advance
