Forgive me if this has been covered somewhere already; a cursory search says it hasn't, but I may have missed it. I have a user query (a saved Advanced Find) that I'd like to retrieve via the Web API, ultimately using the data in Power BI. However, the fields returned when I either execute the Fetch XML (via FetchXML Builder) or via sending a get request via the browser, I get different results than when I run the Advanced Find via the UI, namely, that columns are missing from the results of the two former methods. Any ideas? Below you will find the FetchXML of the query, relevant screenshots, and the JSON returned by the query.

The FetchXML:

<fetch version="1.0" top="10" >
  <entity name="opportunity" >
    <attribute name="elcn_academicprogramofinterestid" />
    <attribute name="createdon" />
    <attribute name="opportunityid" />
    <attribute name="parentcontactid" />
    <order attribute="elcn_academicprogramofinterestid" descending="true" />
    <link-entity name="contact" from="contactid" to="parentcontactid" alias="a_4e29b74a612a43f0969e0b8e08ce7e48" >
      <attribute name="regent_firstcontactdate" />
      <attribute name="createdon" />
      <attribute name="regent_contactstatus" />
      <attribute name="datatel_prospectsourceid" />
      <attribute name="regent_leadsourcedetails" />
      <attribute name="regent_leadsource" />
      <filter type="and" >
        <condition attribute="createdon" operator="this-fiscal-year" />
        <condition attribute="customertypecode" operator="eq" value="200000" />
        <condition attribute="statecode" operator="eq" value="0" />
      </filter>
    </link-entity>
  </entity>
</fetch>
