I used the same version to convert many midis to .nbs files without issues. Maybe you disabled all other bars (or layers?) on accident.
If the song is a custom one, it might have unsupported custom instruments in all the other bars. If you created the song yourself maybe try against importing a midi and exporting that and checking what might be different.
Otherwise it would be helpful to know the exact song. Seems like a rare thing to happen imo, but I could be wrong ofc.
I use OpenNBS 3.10 to export .nbs file. It plays only one bar in the game.
