solar display issue on main WD screen

I have set WD to read data from my Misol station which according to the base unit is a Model WA1091.
It seems to be the same data stream as the WH3081 station.
Now whatever I setup for the solar it always shows a blank solar % insted of W/m2 and 0.6mm ET in the 2 solar boxes on the main display.
Because FreswhWDL needs an upload of W/m2, nothing is displayed as a online solar reading.
How do I check whether the solar/ UV sensors outside are actually sending data as they are supposed to do.
