@dkorolev I cannot reproduce the problem on my side using the latest 22.3 version of Aspose.Words. Here is code I used for testing:

Aspose.Words.Document docOld = new Aspose.Words.Document(@"C:\Temp\old.docx");
Aspose.Words.Document docNew = new Aspose.Words.Document(@"C:\Temp\new.docx");
docOld.Compare(docNew, "TEST", DateTime.Now);
docOld.Save(@"C:\Temp\out.docx");
docOld.Save(@"C:\Temp\out.pdf");
