Splunk shcluster configuration on master not updating config

I am trying to configure a master node in a splunk cluster to be an indexer master and shc deployer. I install Splunk Enterprise (7.3.1) and then execute commands to configure it: splunk edit shcluster-config -secret clustersecret -shcluster_label myshclabel -auth user:pass After doing this, `etc/system/local/server.conf` is updated with a `[shcluster]` heading, but no `pass4SymmKey` or cluster label is configured. it is a blank stanza. I am also running `edit cluster-config` on the server and this is updating the config as expected. My understanding is that these commands should add a cluster label and secret to the config. Am I missing something? Not sure if licensing needs to be configured first? For my use-case, manually editing the file is not an option, it needs to be configured by command.
