I've created a new theme and within that new theme have created a new style. I've updated all of the manifest files and ensured that everything is in the right place and named correctly. However in the admin area I have two styles (which is fine, there should be two). One called Modern, but the custom style I created has no name.
What I see is in the below image. I've updated the manifest.json in the themes root and also the manifest within the styles folder and have created .css, .less and also .png files in the /styles/data folder and I'm having no luck with how to get this to work.
Perhaps I've missed a location I need to edit/include or something?
