PDFEditor Extract - Outlines are not including in target path

Hello,

I am using below code snippet to split the document with bookmarks.
pdfEditor.CopyOutlines = true
pdfEditor.Extract(filePath, 1, 10, outputfile);
Its not including outlines in target path.
Please let me know, how to solve this issue.

Thanks,
Sow
