All Time Record ---- WD Imput issue ----

Hi guys,
i don’t manage to set the date of wind gust speed all time record.
I’ve gone to Action → Enter All time Record menu’.
I’ve set the date and then i’ve click ok.
Unfortunately, it still showing the wrong date in my highlow extreme page: http://www.meteocarmignano.it/wxhilowavg.php
The function is:

$recordhighgustmonth,$recordhighgustday,$recordhighgustyear

Any help please?
Regards,

Alessandro
