Show Autofocus Points feature not working in Camera Raw 18.5 for Nikon D850 or D500 raw files

Adobe Camera Raw 18.5

This problem occurs on both Nikon D850 and D500 raw files which have been opened in ACR by right clicking on the files in the Mac finder and selecting open in photoshop.  The files have not been previously processed in any way.

When I right click on the image in Camera Raw, the option for “Show Autofocus Points” is greyed out and not responsive.  I have repeated this with multiple files from both cameras taken using different autofocus modes.

I have checked two of the files (one D500, and one D850) in Raw Digger to examine the EXIF data, and both show values for “Focus Position” (0x11 on a D500 file) and “AF Points in Focus” (E9 on the same file), so this metadata information should be available to Camera Raw.

Are these cameras supposed to be supported by this feature?  Adobe’s documentation says nothing about what cameras are supported.

I watched a video today showing someone using this feature (although with a different camera’s files), so I know that I was looking at the right menu option.

Thank you.
