Re: creator and author syntax question

I'm not sure if this is the issue, but "creator" would need to replace
"author" in all instances so that the property name inside the Role node
and outside match. This example
<https://search.google.com/test/rich-results?utm_campaign=sdtt&utm_medium=message&id=0i1zgwe8dP6hYxOZoozL-Q>
seems to pass.
