Thank you for your reply.
However, I was able to exchange the newly created Rayquaza (OT: Nobunaga) in PKHeX when I changed the SCALE to 64.
Is this a new law?
There seems to be a misunderstanding because I only included the necessary information.
I did not try to exchange with others, but exchanged between my accounts for verification.
I apologize if I have caused any discomfort...
