Look more globally. Think about what have you done that really made a difference to a team/dept. They're recommending you because they know you have your stuff together, but you have to demonstrate you can work with peers and think more about the store than what you were doing. Your situations need to be focused on what you specifically did, who you partnered with, how you turned the opportunity into a win for the store. It has to showcase your talents and show that you were the reason the situation turned out how it did. If you make it seem others took charge or your situations don't incorporate others, that's the problem.
Think outside the box with your answers as well. My issue when I started interviewing was that I was taking the questions too literally. I had great situations- turning red depts into district-topping green scores- but I never "got the right question". Twist the question and answer it with one of your strong examples. Come up with 5 or so situations that exemplify the leadership expectations.
