I have reported this bug and they are investigating it. However I can
assure you it is purely just a visual glitch and your account will be
whatever the default actually is. I admit it is confusing/annoying and I
hope it is resolved soon!
If it has no commercial value then maybe you should declare it as
"sample" or "gift". Then customs should be free. Take that with a grain
of salt though, I don't fully know your situation or what you are
