In Logics Export dialog to to export the SELECTED midi tracks turn ON the Export Selection as MIDI File switch - but turn OFF that MIDI file switch in case you want to export ALL midi tracks.
I think it is ok to get "ALL" midi tracks, because this format 0 does not have separate tracks like midi format 1, but it has the advantage that all keyboards and MIDI file players can read and play these files.
The correct MIDI channels should also be maintained with "all" tracks, with all the data is stored in one track.
