After opening the photo, I set the magnification to x4 and Face recovery Gen. 2 Creative. With a small exception (the terrible eyes of the no selected woman on the left), the faces are plus/minus OK - see photo.
GP detected 11 out of 12 faces, but one was questionable, and on start select 9/10 faces. So I went into the settings and added all 11 face. After that, the program generated faces again, but made that like from some a horror movie - see photo. Importantly, from now on, no matter what I change in the Face recovery settings (Realistic, Gen. 1), the faces do not change by even a pixel.
Model AI has no matter.
[Edit]
Now I see that Recovery faces makes faces like when function is OFF and click switch On/Off has no effect.
