Fujifilm GFX100 II: Why is it Stopping Down the Lens continually, when shooting aperture is f/1.7?

The Fujifilm GFX100 II has already had quite a few firmware bug fixes. So maybe this is a bug.
Stopping down ruins the view and makes noise
With the 55/1.7 mounted and the shooting aperture set to f/1.7, the GFX100 II is keeping the lens stopped down to f/5.6 or so. This is seen at a glace—just look at the front of the lens.
This behavior makes no sense and misleads on what the taken image at f/1.7 shot would look like. It is a sort of anti-preview of depth of field!
Moreover the GFX100S does NOT behave that way—the lens is always wide open. And AFAIK, all the GFX cameras always leave the lens wide open unless the DoF preview button is pressed.
Adding annoyance to all this, the lens makes quite a fuss when the shutter is half-pressed—that lens diaphragm is far from quiet. The whole affair feels klunky and obnoxious, like some crappy circa 2006 camera.
I’ve gone through all the settings and the user manual, and I cannot find any way to fix this behavior so that the camera behaves like the GFX100S.
* Decision made, now it’s about figuring out how to get it done (cost).
