Endnote iPad renames PDFs when opening in another app

In previous versions of the Endnote iPad app, a PDF attachement could be opened in another PDF editing/annotation app, edited, then exported back to Endnote where it could be added to the record. In the current version, when I attempt to open a PDF from the Endnote iPad app in another app (e.g., “Open in -> copy to iAnnotate PDF”), the PDF is automatically renamed to “Unnamed PDF”, which then must be manually renamed.

Can the previous behavior, which retained the name of the PDF file when opened in another app, be restored?

Thank you,
