Re-enabling an Instrument track and associated MIDI tracks, loses the return output track

1 instrument track and then 4 more midi tracks for a total of 5 tracks.

Disabling this, then enabling it back, the return output track for each midi track is lost.
All channels default to the first return channel. (opus 1 & 2)
