[SolidWorks] Complex assemblies will not import correctly

Using Solidworks 2017 Service pack 4.1 the sldasm files only partially import. Instances, folders, and suppressed parts also mess up the import. Suppressed parts show up from different configurations and mates from those configurations affect parts. Instances of parts from arrays are also discarded in the process.

This issue has been reproduced and tested in 4.19.2 (0.182) and 4.20.2 (4.20E2)

1. Download the attached zip
2. Open the UE4 Editor and create a blank Unreal Studio project
3. Navigate to the Import DataSmith button, click the dropdown arrow, and select Import CAD
4. Import the .SLDASM file

Results: The sldasm files only partially imports assembly data

Expected: Assembly data is fully imported
