stuck in training camp stage 5 final box

[fastluke4]

I am stuck on the chest of stage 5 of the the training camp for the masters series. It requires 20 keys to unlock. 10 with the help of the league. I only have 8. I can not obtain the other 2 since I have already done my other master series and there is not a repeatable level on this stage map except for an overdrive event which only drops keys once(which I have already gotten). It seems I can not advantance. Please help

thanks

Same here! EA dude on the phone yesterday told me I was the first person to experience this, I figured that wasn't accurate.
