Unable to set capabilities with agent installer based installation

I attempted to install a BM SNO with the agent based installer.
In the install_config, I disabled all supported capabilities except marketplace. Install_config snippet: 

capabilities:
  baselineCapabilitySet: None
  additionalEnabledCapabilities:
  - marketplace

The system installed fine but the capabilities config was not passed down to the cluster. 

clusterversion:

    availableUpdates: null

      enabledCapabilities:
      - CSISnapshot

      knownCapabilities:
      - CSISnapshot
      - Console
      - Insights
      - Storage
      - baremetal
      - marketplace
