If I had claimed the bonuses, and I am not saying I have not, then surely it would have been ticked off in some way and not open as it appears to be. I have not knowingly received these bonuses but cannot check back.
Hello!
Even if you don't receive Reward for this or that achievement, you still can open information about it and read what it's about.
As you see, Individual Bonus Menu is unchecked here. More likely, you received this Bonus from the achievement in your previous League as it was stated in the comments above.
