Rescan logs to generate rainfall summary

I had to reconfigure WD after a power failure. I still have all the logs, but WD is showing no data in the rainfall summary box at the bottom left of the screen.

Is there any way I can force WD to rescan the log files or otherwise reproduce the month to date and year to date rainfalls?

you can enter the needed month and year rain totals
from the last totals that were recorded in the logfile
via control panel, offsets and initial rainfall setup
