Cutting confusion… How many back pieces?

Hi! I'm preparing to cut the fabric for my first "Roller Skate Dress". However, I'm already confused. On the pattern piece it says to cut TWO?? of the lining and the back dress piece? I'm reading that incorrectly, right? I should only need to cut ... - 1 Front - 1 Front Lining - 1 Back - 1 Back Lining
