20 shipping labels “ box 1 of 10” not in order. Confused af

So I printed up 10 labels for 10 boxes to send to FBA, got em ready to put on the box and all. So I have 10 boxes it gave me 20 labels assuming I have to put 2 on one box

So you know how the shipping label usually says “1/10” “2/10” “3/10” and so on to indicate box number My labels in order for box numbers are 1to 10 to 1to 6 to 2to 10 to 2to 6 to 3of 10 to 1 of 4 This is super confusing usually when I send 10 boxes it’s 1 to 10 and so on completely in order… How do I know which 2 exact labels to put on each box is there a way I can kinda translate this cause I don’t understand lol

For example I’m in the pdf file for my labels it’s 20 labels down page on the right side of label it goes from box 1 of 10 I scroll down to next label and it says box 1 of 6? Usually when I’d mail multiple the second would just say 2 of 10 and so on
