WTF? There is nothing there! Then, for grins, I used the tool to clean up tracks and Vias and it went away. ???
Changed the setting to show the tracks in outline mode:
Only other info to add is that this was observed with the board in “flipped view”.
ON EDIT: When creating the OP It seemed obvious to me that I had hit “Ctrl+z” to bring back whatever was deleted by the “Clean Up Tracks and Vias” tool; and I neglected to mention that I did exactly that (as well as “Ctrl+y”) to get the Screen-Grabs.
