Previewing PDF

When previewing certain PDF files, some fields are not displaying correctly. When we download the PDF and open the file, we are able to see the expected values. We would like the preview of a file to display the same contents displayed when the file is downloaded, whether this be a fillable PDF or not.

Update: We have noticed an updated error message which appears when users try to preview a fillable PDF form. Attached is the "Attention" message which states that the PDF file is in an XFA format and not a PDF. This is not accurate since it is a PDF file but it just has some XML content. It would be great if this message stated the workaround which is to download and open the file using Adobe Reader where the file can be filled out.
