Pool Party Pals mission is bugged - no credit for winning games in PvP while placing 2 control wards

Trying to complete the Pool Party Pals mission. You place lots of control wards, win the game and get no credit for doing so. (This is a new secret smurf account so completing this mission with a friend is a bit tricky right now.) Can this be fixed please? (I've got two wins with over 2 control wards in normals and they have not been counted. And I really really need that blue essence to get some more champs unlocked, because it is next slow earning BE on new accounts. Pretty please can we get this fixed?)
