5d Mark IV downloading 2 versions of the same RAW file

[WickWelsh]

My 5d Mark IV has recently started downloading two versions of the same shot when I import via Photoshop. I only have one card onboard and the camera shows only one version when I review in camera. I've updated the firmware to 1.33 today, but that doesn't fix the problem.

Any ideas?

Another thought do you have DPP4?  If you don't d/l it and see what it does.
