Aspose.words for reporting services..showing text in vertical

I am using Aspose.words for the first time. Its easy to add the export formats, but when I export to word(docx) all the headlines are shown in vertical. Please help me solving this issue.

Thanks for your request. Could you please attach your RDL report for testing? We will investigate the problem and provide your more information.
Best regards.

I have also attached the sample report after exporting it to Word document. I am using evaluation version and we need to test prior to make any decision regarding getting a license.
In some cases we do not know the length of string in textbox.
Thanks for help.

Thanks for additional info. I will proceed to looking into your issue shortly.
