To see the normal vector on regions simply activate SHOW NORMALS in the HighLighter icon and set ON.. Next click in any region and you will see the arrows.
Regarding edge-to-edge contact "no penetration" it is supported only for 2-D solid plane stress, plain strain and axisymmetric "body-of-revolution" analysis meshing with QUAD & TRIA elements, then forgot at all to use this feature with general Shell elements. Not available yet EDGE-TO-FACE contact "no penetration". Take a look to NX NASTRAN manuals, all is there ...
Here you are an example showing the use of edge-to-edge contact "no penetration" in a Linear Static AXISYMMETRIC analysis using NX NASTRAN (SOL101) solver:
For your information, here you are an example of EDGE-TO-EDGE "GLUE" with Shell CQUAD4 elements after solving a modal eigenvalue analysis using NX NASTRAN (SOL103):
