I remember reading another thread about CNX2 saying a file was 12 bit raw when it was actually 14 bit. I think the explanation of that was that CNX2 was out of date. Unfortunately that does not fit your case because you are already at the latest version of CNX2. I'll try to find that thread later today.
Your meta data shows an strange image size 1632x1080, a full size D800e image is 7360x4912! What do you see when you use some other tool to view the meta data? Right clicking in my Windows 7 (maybe other versions too) and selecting Properties and then Details will show the image size. Maybe something like Opanda or EXIF tool would show the bit depth info too.
