Hello, I have updated my Spire.Doc instance from 6.10.6 to 7.2.4. After the upgrade, I'm now experiencing duplicate footer entries after converting a .doc to .docx and updating the table of contents. The .doc is sent as a byte array. With the 6.10.6 version I did not experience duplicate footers.
HttpFileCollection files = httpRequest.Files;
// Get file content as Memory Stream
MemoryStream ms = new MemoryStream();
httpRequest.Files[0].InputStream.CopyTo(ms);
// Open Document in Spire from a stream
Document document = new Document();
document.LoadFromStream(ms, FileFormat.Auto);
//Convert Doc to Docx
document.SaveToStream(ms, FileFormat.Docx);
document.LoadFromStream(ms, FileFormat.Docx);
document.UpdateTableOfContents();
