Twinmotion Datasmith Exporter Destroying Geometry

I recently started trying to use the Datasmith exporters and have yet to successfully translate a model into twinmotion from either Rhino or Sketchup. They either come in with incomplete/missing objects or the geometry is strangely rotated/misaligned. The attached screenshot shows the issues side by side in Sketchup and TM. Something is going haywire in the export.

Is this a known issue? Anyone else having troubles? Any fixes out there?

Thanks in advance!

Best,
Hans
