As you can see on the screenshot I tested with the latest version and it still does no import the file correctly. It might be due to your geometry being offset A LOT. When I go into edit mode and look at a vertex. It's not even displayed correctly since the coordinate seems to be large. I only see 10'000/10'000. ... Probably too much for curves in Blender? There is no support to import it directly as a mesh so far since usually curves are enough and this is also how a user can select more transparently how curves should be "rasterized" to a mesh.
