Hard Edge won't smooth with Sub Div Doing some modeling with Subsurface Div on and there is a hard edge that simply will not smooth.

I've tried all of the following:

-Verified no dup. verts

-Verified Normals Outside &amp; In

-Checked for Clear Edge

-Tried smoothing Object 

-Loop cut and added additional loop for potential topology issue...

I'm out of ideas, anyone know what could cause this?
With some trouble shooting it appears this could be fixed by increasing/adjusting auto smooth. Per the blender manual the auto smooth angle appears to have a threshold that if broken will consider the edge sharp.
