The higher arpeggiated notes last too long upon playback

When an arpeggiated chord is played and notes in the same chord are played immediately afterwards, it sounds like there is some overlap between the notes resulting in incorrect playback. It seems that the notes higher up in the arpeggiated chord are being held on for their original length and not being released at the same time as the lowest note. An example provided indicates how playback sounds currently and how it should sound.
