Cannot "locally disable" a symptom definition

Hi

I created a new policy that inherits from the vSphere 5.5 Hardening Guide Policy.

On some of the symptom definitions I want them disabled, e.g. that the DCUI service is running on an ESXi host.

I press locally disable on the symptom and save. When I open the policy again, it has been set to locally ENABLE! This happens for any symptom definitions I want to alter for my new policy.

Am I doing something wrong?
