Staad Pro to Bentley Structural

Does anyone know what the best way to import Staad Pro files into Bentley structural is and what format?  Currently I am trying to export from Staad Pro and import with the CIMSteel Intergration Standards format (CIS/2).  However when I try to import within Structural I receive an error stating that the model is unable to import due to the model containing an Analysis model.  Previous steps are as follows:

From Staad:

File>Export>cis/2. export the data and close the export dialog box.


From Structural, new file.


All family and parts are matched up accordingly.

click on import and receive alert with one error.
