Can't select track for multiple audio output (VEGAS 22 & 23)

Hi, i'm trying to render multple audio files at the same time with track selection but i cant get how to properly use the selection feature.
In my exemple under it render only the Track 0 with all audios track in the same file and no other.
I've try without the 0 and i just output nothing

Did you assign each output file a unique filename? (I'm on mobile and can't look at the log file properly at the moment.)

Yes, even with only one output if i select a track it render nothing
