SBC not working

Hi everyone, 

Hi Robin, I am trying to complete SBC “91 + mixed Icons player pick” however when I fill out the requirements exactly as it says it doesn’t work. The rating doesn’t change on the 87 rated challenge and the 88 rated challenge. 

For example I could have 8 players all 87 rated and 3 chemistry per player but it still only reaches a 80 rating. Therefore not being able to submit and complete the challenge. 

anyone got any ideas on how to solve?
