Actual date not possible in AdvDateTimePicker

I use the AdvDateTimePicker (latest version) with a given start date of 01.01.2100. If I click into the AdvDateTimePicker it moves to the actual date(=today). That's fine and ok - BUT: if I move on to the next field (equal which one, by tab or by mouse) it moves back to the 01.01.2100. That behavior also comes when I put in the actuel date by hand. Only if I use another date (i.e. one day before today) it stays at that date. Is this a bug or do I do something wrong?

I could not see an issue.
I initialized with:

begin
  advdatetimepicker1.Date := encodedate(2100,1,1);
end;

and cannot see any unexpected behavior
