Missing Customization information on packing slip

Hello,

I have an issue with the packing slip. When I print the packing slip without buying the shipping label, everything is correct, and I can see all the customized information on the packing slip. However, once I try to print the packing slip together with the label, there is missing customization information. We need to see all the information and this is so weird. Why do I have to print them separately and match them one by one? It would be easier if we could print them together so that we know which label belongs to the packing slip with custom information. Also, it helps us prevent mistakes. For now, we print the labels first then print the packing slip, and then match them one by one. Any help will be appreciated. @Rose_Amazon

Thank you.
