Recently my QTR-Create-ICC grayscale profiles have not been available in Photoshop, Since the Mac, and Adobe, have been playing badly the last year or more I assumed it was a color management problem. But I also have old OS and PS versions, and some weren't showing up either. For a variety of reasons I make a grayscale, and an RGB version of each profile after. doing the measurements, turns out this is the problem. Both versions have the same internal name, and that is what PS looks for. So, it will only recognize one of them. If you change the internal name of one, they will both be available in Photoshop.
