Beckam Chronicles missions bug

Present won't unlock

That means that you have unlocked the nightmare mode after completing the chapter first time 

Badly designed, what about the present?

When you finish the required number of skill games and claim those rewards

Where are they?

All the way to the left

I finished them

You haven't. You completed 9/18. When you finish 3 more days of them and claim those 7/18, 9/18, 12/18 and 18/18 rewards you'll claim the reward to the right

I'm playing every day and they won't unlock, only 7/18 and 9/18 😕
