The issue with automatically created Named Selections in SC has been reported as a bug. The developers will be making a change in the future version to allow the user to "filter" Named Selection import as we do for other CAD.

Workarounds:
 - Export to .sat (ACIS) file, then re-import back into a new SpaceClaim model. 
Or
 - You can shift + select (multiple select) and delete the Selections.
