I was experimenting and tried creating a page template from the page editor by clicking the button below.
I no longer want that template there, as I'm just going to do it the old-fashioned way and manually create a template to upload to my FTP instead.
I cannot figure out how to remove the template from this drop down menu below.
As you can see, there is no template in my site files (child theme), so I have no idea where this lives or how to remove it.
