TomK,
If that color is purple, then it looks normal for "some missing ADSB weather data". Look at pages 7-70 to 7-80 or so in the Pilot's Guide. It says purple means no ADSB weather data for an area.
Both your photos show "no NEXRAD CONUS" received.
Are you new to Skyview? Is your ADSB new? or newly set up? Was the unit on for a while, and in view of ADSB towers the whole time?
I would bet that if it ran for a while, in view of one or more towers, that all that purple would disappear over time.
