Hi geekmidget, that's just a display artifact that should be ignored.

There is a setting under Options > View > Meshing parameters > "Mesh angle", if you set Mesh angle to 5 it will do some more refinement of the display mesh.

But it isn't very good to modify that if you have larger models because the display meshes can get pretty heavy.
