Cutting from the Back will cut with the back of the mat toward the operator, and can be selected on the Cut Preview.
If you are cutting an element that must be applied to the front of the mat, such as a V-Groove or Pen design, any openings on that layer will also cut from the front and use the Front of Mat configuration item; i.e., Normal Bevel-Front of Mat.
So if you are having problems with a Normal Bevel cut on the same layer as a V-Groove, make sure you select Normal Bevel-Front of Mat to edit the configurations for that opening.
