Scaler 2.8.1 in Logic 10.8.1 Live Loops: Chord Sequence Playback Issue - Only First Two Chords After Initial Run

When I set up a Live Loops project in Logic 10.8.1 with Scaler 2.8.1 as a MIDI FX plugin (with DAW sync on), it plays the entire chord sequence the first time but then only plays the first two chords afterwards. What could cause this? (A state file is attached.)

Here is a video illustrating the issue.
