Hi Michael,
Thank you for your update.
On analyzing the given sample, we found that the paragraphs in table are appended improperly which lead to the reported bold preservation issue. We have modified your sample and now, the issue has been resolved. We have shared the sample and generated Word document for your reference which can be downloaded from the following link.
Note: This is not a bug in DocIO, it is a usage level issue.
Please let us know if you have any questions.
Regards,
Dilli babu.
