Doesn't get all info from nfo file?

[freche 0]

I'd like to sort some of my media and for those I have nfo files with sort title however when I add my media to the emby server sort title doesn't get added to the metadata, anyone know what I'm doing wrong?

 

The nfo files for all my media looks like this and the nfo has the same name as the media and are placed in the same folder.

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<movie>
  <title>Aliens</title>
  <sorttitle>Alien 2</sorttitle>
  <collectionnumber>8091</collectionnumber>
  <imdbid>tt0090605</imdbid>
  <tmdbid>679</tmdbid>
  <id>tt0090605</id>
  <set>Alien Collection</set>
</movie>
