Nikon D810 + 85mm f/1.4 AF-D Errors detected in RAW file

I emailed, but now I found the forum, so others can check for same behavior.
 
I've got a new camera, but two of the 100 files I have shot, give an error message, when opening.
I shared 4 files, the first three are using same settings, to validate the corrupt file is not only flagged for its aperture, speed, iso setting.
Then I found an other file, which also gave the same error.
 
Hope this is not a problem with my camera, but since other applications don't complain, I expect it to be this application.
