Teamfight Tactics Reward Claim Bug

I finished 2 missions for the teamfight tactics at the same time, and then when I clicked claim reward on one of them, the other one was just gone, disappeared!!!. So after that set of missions (3 missions), I'm supposed to have 1100 but I only have 1070 points. I tried to log out and log back in, the Teamfight Tactics has a shiny point on it like I have something to claim but when I click, it's already refreshed to the new set of missions (another 3 missions).
