Shading Error or problem.

Hi.

I keep running into a Shading error or problem after I have
used and applied Subdivision Surface to a mesh.
Here are 2 images showing the error or problem.

The Normals are pointing out like they should so that’s not the problem.
Anyone know why this is happening? And even better how to stop it
from happening?



you might try adding another cut ( above the recess ) to sharpen the edge.
