Houdini Engine CitySample

Hi,
I do not undersand where is the bug in my workflow.
Following this City Sample Quick Start for Generating a City and Freeway in Unreal Engine 5 | Unreal Engine 5.0 Documentation
I get some results but not realy wat I expected to get.
For e.g. some of the roof are not filled and the meshes of freeway entries BP are not on the on the right position. They are just stocked on the same place.

Have anybody an advice for me?
