There is no bug that would cause this that I'm aware of.
Which version of the OS are you running ?
I assume in this case you are transmitting both tracks on the same MIDI
channel ?
In which case, both the tracks will be sending a note on for the same note,
on the same channel and both tracks will also send a note off when their
note finishes.
But the behaviour of receiving instruments is not well defined for the case
where the same note on is received twice, for the obvious reason that it is
impossible to do with a MIDI keyboard.
If you have some software that lets you monitor the MIDI stream (MIDIOx on
PC), you should be able to check that the second note off is not missing.
In which case, it is most likely the receiving device that isn't handling
the double note on correctly.
