2 shipping labels?

I am packaging up my Legacy Controller now that I have the EX controller installed. I have 2 return shipping labels which one do I need to use? They have different tracking numbers. Am I supposed to ship something else back?

I got two labels when I did the upgrade but I also got the new servo motors. Avid wanted my NEMA 34 motors so I sent two boxes back to them.

Ok Great. Thanks Garth Need to find a new box. LOL
