Initially I noticed this about a month ago. Waited, because I wanted to confirm my initial suspicions. Confirmed the reproduction scenario on the day of the forum posting. In both cases, I updated a "Write Note" log from October, changing type to "Found It" and the date to the current day (when I finally met the challenge requirements).
Agreed, there is a workaround; However, this appears to be an obvious bug in the code and I expect the fix to be trivial.
Sorry for the late response, I was away on vacations last week...
