Shutting Them Down and Shared Shutout achievement
 

Not a big deal, but if a shared shutout occurs and the score is 10-0 or greater, a Shared Shutout achievement (20 PP) isn't awarded alongside a Shutting Them Down (100 PP) achievement. 120 PP should be awarded instead of just 100 PP.

That's by design. In many cases you only get the highest in a "series" of achievements if they cover the same topic.
