Viewshed - color selection Global Mapper v19.0.2 (b112717) (1) [64-bit] - REGISTERED

Color selection has stopped working in my Viewshed analysis tool.  I select a different color (custom) from Display Color button and run the analysis and it still shows up with the color of the previously run analysis at a different distance (hence the different color).  It was working prior to the latest update I downloaded.

I am new to GM and appreciate all the help.
