Many people, including me, are now confirming you need to complete not 10, but 11 DIFFERENT contracts. You can check your progress in the "MY HISTORY" section of the contracts tab. I suggest looking for easy contracts in the "TRENDING" or "MOST PLAYED LAST WEEK" sections. If there aren't any easy ones, use the search with "ICA Facility Prologue" and "1 Target" options.
FEATURED, TUTORIAL AND (MAYBE) YOUR OWN CONTRACTS DON'T COUNT!
