Knowledge Article visibility in AES

[sdlear]

Hi all, I'm creating an application (just as practice and something to put on a resume) - it is fairly basic, just a store front and some Service Catalog items.

I've created a Knowledge Article for one of the items, and I would like it displayed on the Landing Page in the Portal Experience - I have added the Knowledge Content component in the UI builder.

It displays the default article just fine, however when changing the article sys_id it comes up blank.

The KA I've created has been approved, and published, all within the application scope.

Images attached (populated Knowledge Content is default, blank is my KA).

Any help would be appreciated, thank you!
