Referrer Policy

Without manually adding ‘origin’ to the Referrer Policy, I get this error:

Failed to set referrer policy: The value ” is not one of ‘no-referrer’, ‘no-referrer-when-downgrade’, ‘origin’, ‘origin-when-cross-origin’, ‘same-origin’, ‘strict-origin’, ‘strict-origin-when-cross-origin’, or ‘unsafe-url’. The referrer policy has been left unchanged.

Is it OK that I set the policy to ‘origin’? If there a Plugin Setting I’m missing that is causing this error?
