Lightroom 2015.6: CMYK profiles can no longer be selected for soft proofing
After the 2015.6 update, Lightroom can no longer select CMYK profiles in the soft proofing section of Develop in the "other" dialog. Only CMYK profiles that had been added using previous Lightroom versions still work. It is as if somehow an earlier version of the Lightroom code had been merged into this version. This will need fixing.
