Step 1: Create Solid Feature from which to Cut
When creating the solid on which to work with your Extrude Cut, either create the solid without dimensions, or delete the dimensions before creating the Catalog Feature. Parameters created for the solid may become part of the Extrude Cut Catalog Feature when inserted, and removing any parameters not associated with the Extrude Cut will help prevent this problem.
The Solid does not need to relate in any way to the Catalog Feature. In this case we will be creating a cope profile for a 3/4" board, yet the solid on which we will be working is just an oversized rectangular part.
