Hi，ejeebeats

If ableton live cannot export the complete midi track, you can try exporting the single-track midi file of the main instrument and melody, or the audio split track of the main instrument.
The review verifies whether your certification documents correspond to the music. As long as the midi track or audio track you provide is relatively complete, it will generally pass the review.
(The minimum requirement is generally no less than three-track midi or audio files)

thank you for your understanding
