Content type created but not finding in file properties content type dropdown - SharePoint 2019

I'm in SharePoint 2019 On-Premise, and I've created a site content type. Added it to list form settings. 

However, I can't locate it in the file properties dropdown. The other existing content types display correctly within the document properties, but the recently created one only appears only at the document set folder level. My goal is to have it included in the file content type dropdown. Can someone provide assistance?
