Some autostart apps don't closed on logout

I have 21 programs enabled in "Session and Startup" (all with trigger "on login"), and I noticed that 2 of them don't seem to close when I log out, i.e. N logins result in N running copies of the program. The programs are:

• Geoclue Demo Agent, added to autostart automatically after installing geoclue-2.0 package from the Ubuntu repository. The contents of /etc/xdg/autostart/geoclue-demo-agent.desktop are:

  [Desktop Entry]
  Name=Geoclue Demo agent
  GenericName=Demo geoclue agent
  Keywords=geolocation;
  Exec=/usr/libexec/geoclue-2.0/demos/agent
  Icon=mark-location-symbolic
  NotShowIn=GNOME;
  NoDisplay=true
  Terminal=false
  Type=Application

• redshift, which I added manually using the "Session and Startup" interface (/home/daniel/.config/autostart/Redshift.desktop):
