Team Challenges Bug

After completing a lot of team quests with the same stack we ran into a challenge saying "Play 3 matches" with no amount of xp showing next to it. At first we didn't think much about it but after completing it we indeed didn't get any xp and the same challenge was there again "Play 3 matches" with no xp next to it. Not sure if this is a bug/intended(I hope it's not intended because it's nice to get xp and not run out of challenges).
