I'm no expert but the one I recently installed none of them had that "Notch" , looks a bit ragged in zoom to be there by design , I stand to be corrected but looks like something's been forced in there!

Except for the narrower friction disc they all have the notch marking. Not the best (angled) photo  tbh but they are all marked the same I have arranged them so they are all notch/indentation  side out together so as to speak in the basket slots. The new DS clutch friction plates have the same markings.
