How does the weekly XP work?

I was on top of the leaderboard last week with 100-150 difference between me and the second place. Now (8 a.m my points are at zero, I didn’t got notified about anything but it seems like the other people on the Leaderboard keept theyr weekly xp. Is this normal or just a bug?
