Level 5 Mastery BEFORE S- and NO token

I played a 'normal game' as Taliyah in the jungle and at the end of the game i achieved level 5 mastery, and i also earned an S- . According to the end of game screen i achieved the level 5 mastery before receiving the S- and yet i was given no token.

(The 'mastery guide page' on the LoL website simply says that you must have mastery 5 BEFORE being able to get any tokens, and as the screenshot shows, i achieved the s- AFTER achieving level 5)
