The defensive perks don't last forever. I think there is some kind of glitch with them. Sometimes their numbers will still be highlighted as if a perk is applied for long after the effect of the perk wears off. I'm guessing they last for the duration of the season when they are applied, since they are only relevant to h2h. I can say with 100% confidence that the tough perks I used in the past are not still active.
