(Solved) Surface snapping Game Objects don't work even with Shift + Control.

EDIT : I Solved it, finally, it was just because the toggle tool handle position was on pivot and not on center, i hope though that this can help some people having the same issue as i had. Sorry for that post.

Hi, i just discover that we can snap objects toghether (when they have collider) with V + drag.
But i also see everyone on the internet Snapping the objects on the surfaces with Control + Shift + drag. And that isn't working for me, I even downgraded my version of unity 2019 to 2018 to have everything like the turorial i am watching.

When i do control + shift and drag, my object middle point (like the middle of a cube..) get on top or on the side of the other object. I don't know if you will understand my situation but i would really appreciate it if someone could explain me what i am doing wrong and hopefully be able to correct it.

Here is an exemple of what happen when i try to do it :

Thank You!! It was driving me crazy. As soon as I set the tool handle position to center it worked.
