Checking the obvious first, are your settings for export "current view" and is your section-box view the active view? After that, are those items that shouldn't be there in a link? Links do not get cut by the section box on the export.
Thanks for your quick response. The export setting is "current view" and section box view is in active mode also there is no link. Can you suggest us any other possibilities to solve this problem. We are in real hurry.
