I contacted CGC yesterday by email and by phone today and they are looking in to it, but interestingly if you look up any of the "Blue" certification numbers on CGC's website, they've all been changed to "White pages" with a grading date of today. This tells me it was a mistake and I (and others) have a book with an incorrect label. Not the end of the world, but not cool either. I'm trusting that CGC will do the right thing here and offer to redo the labels (and pay for shipping both ways) or offer a grading credit.
