Thank you for your getting involve of this issue.
Fyi, for NHK side, when they found discrepancy and quality they will check a whole lot but for this case they received the box in the different period from LAT, not the same day. In the first claim, they found 3 of 4 boxes, they checked all 100% , for this claim 48% they already checked, no more box at NHK side at this moment. So, we should also get LAT to be aware of this issue, if discrepancy found, they have to check a whole lot in LAT.
