SOLVED: Trying to set up NFO file for TV show display order

[akirby83]

I'm trying to set up an .nfo file at the root of a show folder to set the display order to DVD, instead of having to alter the show's metadata after I import it.  This is what I'm trying but it just results in the display order being set to blank.  No combination of capitalization or quotes results in it working.  I've read the Jellyfin documentation on NFO files but it's pretty sparse so I'm sure there's some critical information I'm missing here.  Here is my tvshow.nfo code:

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<tvshow>
<DisplayOrder>DVD</DisplayOrder>
</tvshow>
