Hi - was having trouble creating a profile for my new camera for Lightroom, (using x-rite, saving as DNG etc.) and kept on getting the above edit when using DNG Profile Editor. I finally shot the x-rite color checker real tight, which essentially gave me a darker exposure, and that was accepted. Remember that you have to close Lightroom for it to take effect. Martin Evening details the process in his Lightroom CC/Lightroom 6 book, pp. 274-277. I've used specific camera profiles (one for sun, another for shade) for the past 8 years or so - I find a subtlety that none of the canned profiles have, though Adobe Standard is useful also. Just an FYI. Good luck!
