Improperly printed last layers

Hi,

The last layer never prints correctly for this (attached) model. The model does not have any manifold errors.
Notice how their is a void under the last 3 layers where extrusion begins?
Print error
Print error
I have tried all of the following and more:

[*] 100% infill
[*] 30 perimeter shells
[*] Turned off all retractions

The material is PLA. Print speed has been done at 40mm/s up to 70mm/s.

Nothing seems to fix the problem.

Here's the model:
test top.stl

Can someone please suggest how to slice this right using Simplify3D?

The model prints perfectly fine using Craftware but that software is missing some features I need which simplify3d has. Or maybe I'm just used to Simplify3D.

Thanks in advance.

It would probably help more if you posted your factory file (File > Save Factory File)
