Combo nexus wk1

This objective requires 30 assists as well as 20 goals from any nexus player. However for the past 8 games playing on CC, the numbers have not changed. They remain at 8/30 for assists, and 3/20 for goals. I have had enough goals and assists in those 8 games to pretty much finish those requirements. So whats going on. Why no adding of goals and assists? Anyone else experience this problem? Aljo. Can i get a feedback on this.
