Thanks for your inquiry. You have shared the images instead of problematic and expected output Word documents. If you do not share these documents, we will not be able to investigate your issue and provide you information about your issue.
PLD_SZ8 Product Legacy 2015-11-2_B_Draft.docx it self is the problematic doc which I have shared with you in zip file. Whatever the problematic Image I have shared with you is from the same doc (PLD_SZ8 Product Legacy 2015-11-2_B_Draft.docx) just for your reference to know where is the exactly problem in doc.
Please check the section 6.1-6.8 in this doc. you can see the single row of the table in this doc( with the column name owner, assignee etc). And I am trying to add the below row of this heading row which is not getting added in my case.
Thanks.
