AEON Gen 5 4-in-1 Multi-sensors stopped sending the complete message for motion detection

Sometime yesterday, my Aeon multi-sensors stopped sending full motion detection messages. All that is sent now is;

2018-02-19 14:47:58.314 [DEBUG] [ssage.ApplicationCommandMessageClass] - NODE 13: Application Command Request (ALIVE:DONE)

Nothing about a motion detection (or anything related to this node) shows up at that time in the event.log

Since I had first set it up about a week ago, it had been sending these messages;

2018-02-16 17:40:57.880 [DEBUG] [ssage.ApplicationCommandMessageClass] - NODE 13: Application Command Request (ALIVE:DONE)

And the event.log showed;

2018-02-16 17:40:57.882 [vent.ItemStateChangedEvent] - KitchenMotionSensor changed from OFF to ON

I disabled and re-enabled motion in HABmin, then restarted OH2. The full messages started showing back up again. Then sometime later (less than 1 hour), they reverted back to the incomplete messages.

One of the 4-in-1 sensor .xml files is at;

Is this a problem with the sensors, the event handling mechanism, or … ?
