That’s odd. Your style shows as modified but switching to the un-modified style makes the foreground image appear. The only change I can see between it and the original style is you turned off the sky color. Turning off the sky in the original style doesn’t seem to have the same effect.
I wonder if you’ve managed to create a strange, defective style. Go back to the original style in your In Model library and see if you also get the foreground image back.
