When you double-click, it opens ACR via Photoshop. When you "Open in raw" it opens ACR via Bridge.
Make sure you go to both programs (Bridge and Photoshop) and choose "Updates" from both Help menus, to make sure everything is current.
Before we explore more complex fixes, let's not ignore the easy solution that might exist - do you have another photo of his head, at the correct size and angle, that might be suitable for a swap?
I wonder if the images are appearing in a different order on your screen than mine? I see a couple of photos like that, but both are on the left, not in the middle.

Yep, that's what I was thinking too. And it's easy enough. Just sample the sand colour with your eyedropper tool, then add a Solid Color layer of that colour, and set it to "Color" blend mode; then mask on carefully.
