Jellyfin picking up wrong audio channel as default

[felix920506]

I have some mkv files with the following layout:
- HEVC Video Stream
- Opus Audio Stream (Main channel)
- AAC Audio Stream     <-----
- AAC Audio Stream
- PGS Subtitles
- PGS Subtitles

All audio channels have their default flags set to yes.
Jellyfin is picking up the second one (The one with an arrow) as the main channel instead of the first one (The Opus one)
Is there any way I can fix this?
