CLI universe package install works but not UI


I followed the documentation for version-3.x of the Mesosphere Universe to create a local universe on my DC/OS cluster and added a single, minimal package to it. I was able to successfully build the new universe and am able to see my package in the DC/OS UI however when I hit the install button I get an error for "Invalid Configuration: The schema for this package is not properly configured. If you are the package owner, please check your configuration. Or you may contact the maintainer". However, I am able to successfully install the package on my cluster by using the "dcos package install" command, so the schema must be properly configured.
