Infopath forms submitted to SDP - Not all fields displayed

Infopath forms submitted to SDP - Not all fields displayed

We have some InfoPath forms which users submit to ServiceDesk Plus.  However, not all the fields are displayed within SDP with the completed content. 
 
The missing content relates to fields which look up information from Active Directory.  They display as an empty image-type field when submitted as a SDP request   Data is entered manually for the remaining form fields.
 
How can I get the fields which look up AD to display with the correct information?
 
Update: Since my initial posting, I found this previous discussion on the forum https://forums.manageengine.com/topic/can-i-use-an-infopath-form-for-creating-requests? although it doesn't answer my question about displaying the AD fields.
 
Our SDP is configured for a Windows Domain Scan which points to our domain controller.
 
Thanks.
