  6. modify wallpaper selection to Dynamic

Explanation:

Starting macOS Catalina the system prefers Dark still image on dark appearance. Due to bug 2 overlaping popup buttons are displayed. For images inside System/Library/Desktop Pictures/ the disableCustomPlacement is set to YES (this makes the other popup to be hidden) . All other locations will have this property set to NO (this causes 2 popups to be displayed).

 Derived Properties:
     pictureChangeIsActive:  0 
     canSetBackgroundColor:  0 
     disableCustomPlacement: 0 >
Debug panel
