Spinnaker keeps showing disabled stages in Jenkins pipeline UI

I have a pipeline with a few disabled stages:

{"enabled": false,"completeOtherBranchesThenFail": true,"continuePipeline": false,"failPipeline": false,"parameters": {"FOO": "bar"  },"type": "jenkins"}

The doc states that disabled stages are hidden from the UI [1]:

enabled - Determines if stage will be available in the UI.

However, those stages are still present in the UI.

When I go to Configure Pipeline> Edit stage as JSON, the enabled flag is set to false, so the UI has the right value.
