We are trying to update the table of content in a word document using Aspose.Word 21.4, but i see question mark for some randome word files under table of content. Could you able to assist in getting rid of this problem.
Please upgrade to the latest (21.9) version of Aspose.Words for .NET and see how it goes on your end? In case the problem still remains, then please ZIP and upload your source simplified Word document and Aspose.Words generated DOCX file showing the undesired behavior here for testing. We will then investigate the issue on our end and provide you more information.
