How to restore the rain data

I know there is a youtube video for this but before I do something stupid, I ask here. See the screenshot ( http://www.vremetolmin.si/temp/rain_data.png ) . My rain data was recorded just fine until something happened (?). What should I do to get the values back? The main WD screen shows the yearly rainfall 0.6mm (that’s what it is today).

Question 2: last year, there was a general bug where the December rain data was not correctly calculated (it repeated the November’s amount). How can I recreate the NOAA report and other reports?

Thanks.

you can set/reset the needed year rain total via control panel, offsets and initial rain

for question 2, make sure the rain total is correct for those months, under view, rain chart
(i.e you can edit the month rain totals there)
you can recreate a noaa report (there is a youtube video on that)
