My pokes are getting EVs they shouldn't be. I just horde trained shroomish on Trevenants, and his graph showed he had max attack. I then decided to train a kangaskhan and gave give the Power Bracer and Shroomish the Power Anklet (Atk and Spe respectively). Now after training on Trevenants again my Shroomish has gained a shit ton of Speed EVs for no reason.

Do power items convert all gained EVs to their corresponding type now? Can someone else confirm this?
