Would you know the location of the short and long author list?
One field is part of the normal PDF structure. In your case it contains the short list. Adobe Reader shows quotes around this data if certain delimiters are contained in that field.
The other field is part of an XML file with meta data that is embedded in the PDF file (XMP). Adobe Reader does not add quotes when displaying this field. In your case it contains the long list.
At some stage those two fields got out of sync.
PDFsharp does not support XMP yet.
Open the PDF in WordPad or other editor and search for "UserA" to see where it occurs.
