Document generation of a repeating section within a repeating section

We have a form that is a candidate for multiple/nested repeating fields, as it looks like this:

It has been requested that I find a way to have this be a generated document. We have Nintex Forms and Workflow for 365, and I found a similar use case:

Diving a little deeper into Document Generation

But when I look at the XML I get from these nested sections, this is what I have:

reportTopic1discussion1<?xml version="1.0" encoding="utf-8"?>
<RepeaterData><Version /><Items><Item><ActionItem type="System.String">actionItem 1.1</ActionItem><PersonsResponsible type="System.String">people 1.1</PersonsResponsible><Deadline type="System.String">deadline 1.1</Deadline><Status type="System.String">On Hold</Status></Item><Item><ActionItem type="System.String">actionItem 1.2</ActionItem><PersonsResponsible type="System.String">people 1.2</PersonsResponsible><Deadline type="System.String">people 1.2</Deadline><Status type="System.String">Open</Status></Item></Items></RepeaterData>

1. reportTopic1discussion1
2. <?xml version="1.0" encoding="utf-8"?><RepeaterData>  
3. <Version />  
4. <Items>  
5. <Item>  
6. <ActionItem type="System.String">actionItem 1.1</ActionItem>
7. <PersonsResponsible type="System.String">people 1.1</PersonsResponsible>
8. <Deadline type="System.String">deadline 1.1</Deadline>
9. <Status type="System.String">On Hold</Status>
10. </Item>  
11. </Items>  
12. </RepeaterData>  

So, how can I grab the things that start kind of before the XML (which is the "parent" Repeating Section)? Or is there a better way to do this that I'm missing?

I configured the parent repeating section to be the one that points to the plaintext multi-line field, and then could not do so with the nested one.

Parent:

Child:

I can't configure the child to be connected regardless of whether or not the parent is either, as I did check.
