By the data in Metadata tab I see that the lens is not assigned and I suppose you can have a module ambiguity for this image (when several lenses are supported) and a yellow icon like this:
When you click on the icon and select the proper lens -> you’ll get Lens sharpness sub-palette.
Hello Robert,
have you checked that you have “ticked” Lens Sharpness for this palette? In the “Detail” palette, click on the little downward arrow to the right of the word “Detail”, make sure Lens Sharpness is ticked.
