GUIDs of IfcBuildingElementParts altered in Power BI Stream?

The GUIDs I get for parts after loading the stream in BI within the Power Query seem to not match with the actual GUIDs I see in the webinterface and in other IFC-Viewers … for other elements it is matching but not for the parts. Why and how can this be?

Actually I am still confused which stream to take as there is a difference between the old and the new viewer?

So it seems like in the light version there is the correct guid, but in the dark version it is not but I can’t use the share link of the light one as then I get the following error message:

Expression.Error: The branch ‘main’ in stream 123241243 has no commits

So please let me know about the latest workflow so that I can get the correct data as I am confused.
