Flat rate box autofills as Ground Advantage

Question

Hello,I am revising my ad to ship my item via large flat rate box. When I do this, Ebay autofills the Primary Shipping box as Ground Advantage. From what I am reading from the USPS site, Flat Rate Boxes are to be mailed Priority Service and that shipping one via Ground Advantage is illegal.How do I get my listing to be Priority Shipping instead of Ground Advantage when Priority Shipping is not given as an option?TIA,BWSwede

When you create the listing, select carrier packaging and not custom packaging. The priority boxes should then show up.
