My player card does not specify a site or creator. I’d prefer to avoid setting the site and the creator is often unknown. The documentation states that both of these are optional.
When viewed in Chrome, there’s an empty box where I believe one of those would be displayed. The box does not appear in Firefox.

Here’s the URL that’s scraped
Is this a bug, or must I specify the site? Thanks.
