We have fixed this in v10.0 which will be released early next month. If you need early access to this release, you can sign up for the prerelease program from https://adobeprerelease.com under NDA.
Select Adobe Bridge. Once we approve your request, you will be able to download v10.0 (choose the latest drop).

One further query ? My Nikon D850 produces NEF files of approx 93 Mb as shown in the camera and in Finder, when opening the file in ACR the information shown in blue beneath the image preview shows the file size to be approx 45 Mb, I have looked but cannot see anyway to allow the correct file size to be shown, I may have missed something
