TMP75: TMP75AIDRInternal structure update? Weld point update?

Part Number: TMP75

Everybody is good! Can you help me with this problem? The internal structure of the two batches of materials is inconsistent after we purchased them. The model is TMP75AIDR. Before, we received a document from the buyer saying that the welding point was changed. Is there any problem with PCB? Is there any documentation to prove the same thing? Attached is the picture under X, which is different from the welding points in the document.
