Problems saving an E-size SolidWorks drawing as a dwg file - borders do not match

We are having trouble with saving a SolidWorks drawing (E-size) as a DWG file - when it is opened in DraftSight, the paper sizes are not matching.  Is there an option to change this?  We've used this method before with other size drawings without a problem.

When we go to the options, it does not allow us to change the size.   Is there a way to change this?

A pdf file showing the issue is attached.

Any assistance would be greatly appreciated.

Thank you!
