The document you attached doesn't contain any repeating xml content, nor any Sharepoint-injected xml. And the two dropdown CCs contained in the body aren't mapped to your custom XML (which also doesn't contain a node named to align with either Key Personnel or Support Staff). As a result it isn't clear where you think this list information is going to come from nor to what the user selection might map to.
I do see you have mapped CCs in the footer but these aren't dropdowns.
Code:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?><AQ_CustomProperties xmlns="http://schemas.aq.com/customDocProperties">
<AQ_ProjectName></AQ_ProjectName>
<AQ_ProjectNameShortVersion></AQ_ProjectNameShortVersion>
<AQ_ProjectNumber></AQ_ProjectNumber>
<AQ_ReportTitle></AQ_ReportTitle>
<AQ_ReportTitleShortVersion></AQ_ReportTitleShortVersion>
<AQ_SpecDivision></AQ_SpecDivision>
<AQ_SpecSectionName></AQ_SpecSectionName>
<AQ_SpecSectionNumber></AQ_SpecSectionNumber>
</AQ_CustomProperties>
Psst: It is a very bad idea to map a Rich Text CC to your custom XML.
