Notes do not release together in Swing or Shuffle mode

Steps to reproduce bug
1. Open release.mscz
2. Play the attached file listening to the release of the half note in measure 2
3. Bring up the F11 play panel, and listen again with the straight, swing, and shuffle effects.

Expected behavior: since the half notes are the same in measure 2, you would expect them to release at the same time in all 3 instruments, no matter what effect it is played in.

Actual behavior: The release sounds correct for the straight version, but when changed to swing or shuffle, the bassoon and oboe release much sooner than the flute, probably something do do with the tie from the previous measure.
