The clipping occur as those animation uses same collider size as standing animations so they clip through the floor below. Fortunately this won't be the case in the new build.
As for the jumping it is working as it was suppose to when you hit the ceiling and the whole level 10 will be reconstructed.
Let me know if you find any other bug that I will need to put attention to.
