Created a concurrent program and set output as XML but nothing when clicking on show output

Hello,

We are on Oracle EBS 12.2.4.

I created a concurrent program and set output as XML and the process completed normal.  However, there was nothing when I clicked on view output.  IE form did open but there was nothing (blank).  More details:

•   In log file the output has something in it (782 bits). 
•   When I clicked on view source from IE form and I could see the output in txt format.
•   When I set the output as text for the process, run the process, then clicked on view output, I could see the output in text format.  So it seems like Oracle EBS just won't format the output for me.
