I suppose this is a sort of bug fix request - not that it is a bug as such, but a part of an object that should not be there. On the Kitchen Cabinets corner unit, there is a flange, part of the bottom of the toe recess I presume, that still shows when the toe recess is displayed and displays the cabinet texture fighting with the floor texture. It shows intermittently depending on the angle of the camera but shows when rendered. The other cabinets do not have it.
It is easily fixed by lowering the cabinet into the floor a fraction (and doing the same with the other to match) but it would be nice if it could be removed.
