Avidemux doesn't keep both audio tracks

[Reading Bug]

Hi all,

I'm having the following problem I can't solve on my own and Google doesn't give anything.

I have an M2TS file with two audio tracks: an LPCM and an AC3. I'm looking to copy without re-encoding (need to make some slight edits) but the output file will only retain the AC3 track no matter what I do in Audio > Select Track. The main window indicates 2 tracks selected but only outputs the AC3. Here are the source file details.

How do I output both tracks please?

One thing to try is to repackage your m2ts into an MKV using mkvtoolnix,
then use this new file as your source
