Clearing Rain Data- Zephyr PWS-1000

[AZDesertRat]

I recently installed a new weather station and Cumulus software.
When I first set it up the rain gauge registered a couple inches while I was testing it all out and mounting it on the pole.
How do I clear than incorrect historical information and transfer the correct year to date number from my old La Salle station and Heavy Weather software this one replaced?

What I did is under "EDIT" at the top of the program click it, you should have a thing pull down. At the bottom of that there's a "Today's rain". In here put 0.000 in the box next to "Desired total".
