Ecowitt / Rain Gauge - sensor error values?

I have an Ecowitt GW1100 connnected to a Weather Station as well as to a couple of freezzer sensors. For the Weather Station, the sensor “Daily Rain Rate” is a bit muddled.

As per screen cap the rain yesterday was 5.11 mm…and then the sensor reset at midnight to 0. It drizzled overnight (0.2 mm) and then…all of a sudden, jumped back to 5.11 mm although there was NO further rain.

I have another sensor that totals the monthly volume and it seems to accord with the screen cap…ie it adds the incorrect value to the total.

WTF? This doesn’t make any sense and it’s not the first time I’ve had anomalous results. The other day we got to 1.8mm and it then poured…but the sensor value didn’t ever change.

Am I doing something wrong or is there an issue?
