Which specific value is invalid?

=====

It looks like the UPC one. If it is this, then the UPC code you used before may be from an informal channel, such as buying it from Taobao or other website forums to generate the UPC. . . . In fact, this thing is not expensive, so it is better to buy it from the official backend of Amazon, which is more reassuring.

Of course, since I have never operated the backend of the Japanese site, I am not sure what this item is called on the Japanese site. You can check which specific value is invalid, and then you can go to the customer service to ask what the situation is or fill in the value. It is still very simple.
