Windchill e-mail warning subject line

I have set my WD to inform me if the low windchill goes below -10C. On Christmas Eve I received an e-mail which said, ‘Menstrie AWS WEATHER ALERT -100C min windchill was reached !’

Either there are too many zeros or there is a decimal point missing in the subject line. The value in the e-mail was -10.1C

Does anyone know if and where I can correct this myself?

Regards and seasons greetings to all.
