Check the attached video DeleteField-FilterResultsMacro.mp4 for a recording of the issue's reproduction.

Resolution

Upgrade Jira to the upcoming Jira 8.14 release.

Workaround

It is possible to remove and reorder fields using an additional plugin from Atlassian Marketplace called 'Source Editor'.

1. In the Confluence user interface, select 'Confluence Administration' from the top right, then 'Manage Apps'
2. Click 'Find new apps', and in the search box type in 'Source editor'.
3. In the search results, find this one :
   
   (You can also find it in the Atlassian Marketplace - source editor)
   Click 'install'
4. Wait a few seconds and close the popup that says it's installed
5. Load the Confluence page with the problematic macro on it
6. Edit the page (but don't click 'edit' on the macro)
7. In the top right corner, click on the '<>' icon (Mouseover will show 'Open in source editor')
8. The example below shows the default columns, plus a new one that I added 'Created': Type, Key, Priority, Summary, Created.
9. The macro block itself is within the <ac:structured-macro> tag:

   <p>'Filter Results' macro added from Jira:</p>
   <p>
     <ac:structured-macro ac:macro-id="7a4a1ab1-3113-432d-8158-904056e9d433" ac:name="gadget" ac:schema-version="1">
       <ac:parameter ac:name="filterId">filter-10002</ac:parameter>
       <ac:parameter ac:name="isConfigured">true</ac:parameter>
       <ac:parameter ac:name="preferences">filterId=filter-10002&amp;num=10&amp;columnNames=issuetype%7Cissuekey%7Cpriority%7Csummary%7Ccreated&amp;isConfigured=true&amp;refresh=false</ac:parameter>
       <ac:parameter ac:name="columnNames">issuetype|issuekey|priority|summary|created</ac:parameter>
       <ac:parameter ac:name="num">10</ac:parameter>
       <ac:parameter ac:name="refresh">false</ac:parameter>
       <ac:parameter ac:name="url">http:/testmachine.atlassian.com:8080/jira/rest/gadgets/1.0/g/com.atlassian.jira.gadgets:filter-results-gadget/gadgets/filter-results-gadget.xml</ac:parameter>
     </ac:structured-macro>
   </p>
   

1. Using the source editor, remove or rearrange the fields/columns that you wish to remove or rearrange from the macro. For example, to remove the 'Created' field, we just need to change the two lines that reference it, changing:

   <ac:parameter ac:name="preferences">filterId=filter-10002&amp;num=10&amp;columnNames=issuetype%7Cissuekey%7Cpriority%7Csummary%7Ccreated&amp;isConfigured=true&amp;refresh=false</ac:parameter>
   <ac:parameter ac:name="columnNames">issuetype|issuekey|priority|summary|created</ac:parameter>
   

   To:

   <ac:parameter ac:name="preferences">filterId=filter-10002&amp;num=10&amp;columnNames=issuetype%7Cissuekey%7Cpriority%7Csummary&amp;isConfigured=true&amp;refresh=false</ac:parameter>
   <ac:parameter ac:name="columnNames">issuetype|issuekey|priority|summary</ac:parameter>
   

1. Click 'Apply' in the bottom-right corner of the source editor, then 'Update' to save the whole page.
