I read on another forum this is a problem the developers are working on. In the meantime make sure you're not playing at a pro level, be all-star or more, and make sure you're not also being a bad player while scoring goals, and do what you are supposed to do. Positioning matters, so don't be a defenseman who's never back when there is a play coming down. If you're a playmaker make some assists too. If you're an enforcer have some fights. Don't take too long of shifts, don't take too many offsides. Don't take too many penalties. Block some shots. If you're out for PK clear some shots. It's more than just goals that counts. Try those until the bug is fixed if you'd like.
