ADL: mismatch between AD4 and vina resuts

Dear all,
I was initially using ADT4 for protein-ligand docking and I got four clusters with the best binding energy(B.E) being -7.0. When I tried using vina, for the same grid box parameters, I obtained a B.E of -9.9 and the position was very different from my AD4 results. why is there a discrepancy between the results of AD4 and vina?how can the binding energy vary so much?
Kindly explain me this issue.
Thanks for your help in advance
