The Earn XP Challenge doesn't count bonuses such as Daily Raids, Twilight hours, and the seeding bonus. As seen in the first image, I have 30 Xp earned and ---291 xp. In the second image, which is after a update on XP, I have 60 Total Xp earned and ---426, which is a difference of 135. In the 3rd image, its just showing the bonuses.
I know the Daily Raids doesn't work from the first 30 XP, which I got from Time Alive on MVM earlier.
