CrossRef XML plugin Automatic Export metadata

Hi! I’m looking for information about what metadata fields are exported when the CrossRef XML plugin is set up to export automatically and I don’t see anything in the documentation or forum.
I ask because we are on OJS and I just noticed that some article metadata such as abstract and licensing is not showing up in CrossRef for an article that was automatically registered, but I can see the information if I do a manual XML download. See for example What’s real is immaterial: What are we doing with new materialism? | Aporia Crossref Metadata Search
but in the manual export of the XML, these fields appear see:

I’m wondering if this is something to do with our setup or with the plugin? Thanks!
