Mzzle - If you win a HD Event (perhaps what you are calling "PvP battle as defense") while you are currently Researching an Objective - it will "register" that you "earned EP" but since you can't "Bank / Save EP" the EP Earned is lost. This is normal and not an issue.
Also, like Boog stated, you do not earn EP for PvP Defensive Wins (when another Player attacks your Base), but only for PvP Offensive Wins (where you attack another Player's Base).
