Right now, I'm trying to edit a world file so that it includes several light sources upon launch. I based my custom light source on the Sun model's SDF file minus the tags. This is what my .world file looks like:

<?xml version="1.0" ?>
<sdf version="1.4">
  <world name="default">
    <!-- Light sources -->
    <include>
      <uri>model://odg_light_source</uri>
      <name>odg_light_source</name>
      <pose>0.8 -2 5 0 0 0</pose>
    </include>
    <include>
      <uri>model://odg_light_source</uri>
      <name>odg_light_source_0</name>
      <pose>1 -4 5 0 0 0</pose>
    </include>
    <!-- A ground plane -->
    <include>
      <uri>model://ground_plane</uri>
    </include>
  </world>
</sdf>

Even though I specified the pose to spawn in and different names for each light source, the .world file only spawns 1 light source at (0, 0, 0) upon launch. Is there a way to fix these two issues (can only spawn 1 light at only at the origin)? Any help would be greatly appreciated.
