Why are the sticker sheets missing in the skylanders superchargers dark edition starter pack for wiiU? How are we supposed to keep track of our collection with no sticker sheets ? Is anyone else having an issue with this? Should I return back to the store

Hello can someone please help !! I just picked up my skylanders superchargers dark edition starter pack for wiiU.

I Was wondering why are the sticker sheets for starter pack (2characters , 2 vehicles & kaos trophy missing?) how are we supposed to keep track of our collection with no sticker sheets??

I Bought a couple other characters and vehicles and they had their sticker sheets. Is this just an error or is my set missing them? Should I return this to the store ???    pls help!!

thank you kindly.
