Having set a reminder on a PDF file, I went to change the date/time, and then the alarm type.
After (apparently) successfully changing the alarm, it snapped back to the original settings within a few seconds.
I watched the timing of this change, and noted that it happens at the same time automatic sync is invoked. Apparently, because I sync this DT3 database (using DropBox), everytime the automatic synchronization takes place, the reminder is returned to its original state.
