Parts of Buildings Not Importing

[ThatSimPilot]

I am trying to create a model from the OSM data and only parts of the buildings are importing. The buildings are the key thing I am after and are definitely on OSM (I tried to edit and add; they were already there). For reference this is the domestic terminal of Brisbane Airport.
I have included a pic for reference but there is supposed to be terminal (building) connecting the middle bridge and each gate/concourse. Any solutions?

Hi @ThatSimPilot

It's mapping error. The terminal building must have a separate contour with the tag building:part = yes. Please refer to the OSM [Simple 3D Buildings](Simple 3D Buildings) specification.
