Hi, Chad.
That's a known issue which is fixed in 4.1. For now, you can use this patched WAR I'm attaching to this post.
You'll need to stop "identity" service in your container and drop the attached file at `/opt/gluu/jetty/identity/webapps/identity.war` location, overwrittig the old file (please back the later up first, in case you'll need to revert the change). Then start the service again, and this shoudl be it.
