GarbCAD change model and support layer.

We have printed a model on our Stratasys F170 but it has gone completely wrong with support and building layers.

When GrabCAD shows the print, it looks right. but the finished product is filled with building layers where there should be no building layers.
If We use slice preview, We can see that there are building layers in between, Can We remove these building and support layers ??

You can compare the problem, to if you printed a cup and it was then filled with building lay inside
