Z-Suite Problem

Hello everyone I present my problem with the program z-suite:
When I go to do the slicing object inside me remains "empty" as if there were no infill. What can it be? (I am attaching pictures of the settings and how it is rendered.
In the first picture are the settings I used, then infill full (so in theory I should do "full" the cube.
In the second image the cube seems to be ok but .....
In the third image shows you how the cube is empty in the center. In practice he print only the first 3 and the last 3 layers
sorry for bad english (i use google translate)
Z-Suite V. WIndows 8.1

That is fine.. Z-Suite won't show infill..
