Hi Mike,
Thanks for your inquiry.
Could you please upgrade to the latest version of Aspose.Words i.e. v11.11.0 and let us know how it goes on your side? You can download it from the following link:
In case the problem still remains, could you please attach your sample Word document and code here to be able to reproduce the same issue on my side. I will investigate the issue on my side and provide you more information.
Best regards,
