Hi Wuttipol,

Thanks for your inquiry. We have tested the scenario using latest version of Aspose.Words for Java 15.12.0 and have not found the shared issue. Perhaps, you are using Aspose.Words without license. Please note that in evaluation mode there are some limitations applied. E.g Aspose.Words injects an evaluation watermark at the top of the document. The document's content are truncated after a certain number of paragraphs during import or export.

Ok, Aspose Team.

Let me try and this jar file.
Actually, we have license.
