When I have any image open and click the channels pallete, my last 3 are not in grayscale. First one is normal(rgb) but my individual red,green and blue ch. are not greyscale. This happens all the time and its not from having more then 1 ch. selected at a time. I can have 1 ch selected say the blue ch only. The thumb nail is bright blue(not greyscale). This happenes for the 3 individual colors. Is there a setting that can fix this because it didnt always be like this. It is hard when cutting image out, cant tell contrast. Please help
