2 audio tracks, only 1 track name

Suggestions
1

Another suggestion: I put a video with 2 audio tracks, but I can only name one of them because only one appears in MKVToolNix!

This doesn’t prevent me from creating an OK MKV with 2 tracks, but I can’t name the 2nd one.

Example of what I would like to do:

Track 1, name: Remix

Track 2, name: Original

Thank you.

When you’re sure that a file contains two audio track but MKVToolNix only shows one in the GUI when you add the file to it, then chances are the second audio track isn’t supported by MKVToolNix, or it’s damaged somehow. Make sure that the file in question actually does contain two audio tracks, e.g. with MediaInfo. Post screenshots of what MediaInfo shows for audio tracks for the file, too.
