It isn't clear to me what you are referring to. Could you be a little more specific?
Jim, thanks for responding. I figured it out. It was a LR setting that I
had unwittingly turned on.
The reason I asked is because there were no red spots in the photo that you posted, and I thought you were trying to illustrate the problem. Red spots indicate that you have your highlight clipping indicator activated so that any highlights that are clipped can be identified. I have both of the highlight and shadow clipping indicators activated all the time so that I can adjust those areas and eliminate clipping wherever possible.
