Page properties report macro not behaving as expected

Steps to Reproduce:

1. Create the following page in Confluence; and give it a label of "Policies"

   <ac:structured-macro ac:name="details">
     <ac:rich-text-body>
       <table>
         <tbody>
           <tr>
             <th><strong>Policy number</strong></th>
             <td>something</td>
           </tr>
           <tr>
             <th><strong>Policy application</strong></th>
             <td>Organisation</td>
           </tr>
           <tr>
             <th><strong>Policy category</strong></th>
             <td>Finance</td>
           </tr>
           <tr>
             <th><strong>Authorisation</strong></th>
             <td>Chief Financial Officer</td>
           </tr>
         </tbody>
       </table>
     </ac:rich-text-body>
   </ac:structured-macro>
   

2. On a seperate page within the same space, add the following content:

   <h1>Policies</h1>
   <p><ac:structured-macro ac:name="detailssummary"><ac:parameter ac:name="label">policy</ac:parameter></ac:structured-macro></p>
   

3. Verify the report is shown correctly.
4. Double click on the macro to edit the report
5. In the "Columns to show" field, enter "Authorisation"
6. Verify that while the column header shows, the content field does not.

Expected Behaviour

The content should be shown for this column, but it is blank instead.
