Challenge doesnt achieveing act progression

On of the challenges in current league depends on act finishing it's called Act adversaries II. i finished my campaign and noticed it: acts 6,8,9,10 achieved and act 7 is missing. i clearly cant skip act and did all of it, i tried to kill final boss of act 7 another time, nothing changed. Maybe problem is that i didnt talk to Sin or whoever after killing Arakaali and just go on to the next act.

24 hours later find it fixed, dont know if that was a support or somehow it fixed itself, thanks anyway
