Power play bug issue

When playing in the franchise mode there is a bug when you select Sim Game. When your team or the computer team receives a 4 minute double minor penalty the Power Play only lasts 2 mins. The other bug is when a team receives a Power Play on a two minute minor it does not end when the PP teams scores a goal it continues to keep the team on the PP for the full 2 minutes no matter how many goals are scored. If I could send a video I think it would better explain.
