Navisworks metadata help

Hi,
I am exporting models from Navisworks as datasmith, but not all metadata gets transported to Unreal. I have checked, and not all metadata tabs from Navisworks get to Unreal. There is one tab - Autodesk Material - that has 2 elements in Naviswork and results in more than 100 elements in Unreal. When this happens the metadata I need gets dumped I guess in the import process. I have noticed that the number of metadata elements never exceeds 200 on the unreal side. I can only say that I am getting only the first four tabs from Navisworks.
What can I do to solve this matter?
Can I bypass some Navisworks Tabs in a Blueprint or Python script?
