In All Time Records, everything looks OK, but when you click “THIS MONTH”, the two fields for warmest November night temp and the coldest November temperature have disappeared.
NOW - press “back” and you will find that this information has also been cleared in the ALL TIME RECORDS too.
If you go back to view to reenter, you will find ALL TIME RECORDS ok again, but the same will problem will reappear again when you again access THIS MONTH.
