Word .docx appear in binary format

[tholland]

Hello, We have recently upgraded our IIS/.Net server to Windows Server 2019. I've upgraded from Spire 7.11.1 to Spire 10.9.6.0. When I now use doc.SaveToFile(document, Fileformat.Docx2013). The documents appear to save as binary (smaller kb size - Like Word 97). After I physically open the word document with Microsoft Word 2019 and save again, it appears to save in a normal docx format (larger kb size). I have attached the Test document, Output Document, and a pdf of a compare of the documents using BeyondCompare to show it appears in binary format. I'm looking for assistance on why they are showing as binary.

Code:
Document documentOrg = new Document();
documentOrg.LoadFromFile(docXProposalOrgFileDocument, FileFormat.Docx2013);
documentOrg.UpdateTableOfContents();
documentOrg.SaveToFile(docXProposalSaveFileDocument, FileFormat.Docx2013);
