Potential non-fatal geometry processing issues

[Moult]

There are a series of non-fatal, but very strange geometry output when this particular file is processed by IfcOpenShell.

File is here: https://drive.google.com/file/d/1BNykQB4wYe8jc3dTrzqP2SFzsxMTagcQ/view

(sorry, it is 150mb, no smaller version)

See the output in Blender (some failed booleans, some very strange circles appearing in all sorts of places)

The same file viewed in XBim:

The following guids have issues (there are more, but this is a sample):
