> Training and validation data not in sync for clarity

Am I the only one who is facing the challenge that best parameters of grid search (CV)are not performing well on leader-board and the parameters which are performing well on leader-board are way down in grid search list of cross validation.

Any help!!!!!!!!!!

May be due to overfitting?
