AA did the same thing when they were converting the 12 (or 13?) 772 with 45J to 37J, I didn't report it at that time but I did mention this yesterday on a private FB group when someone notice it on the 787... a day later we see a new post from Ben
As JDiver said, this is good until they finish with the conversion, which I sure they will finish by the end of April or mid May.
