In your first screenshot, the 'Default' template for your site is 'Uber - Default'. You've created your files in the JA - Social template folder though.
Please move your template override files to the 'Uber - Default' folder. Then, you should be able to see and select your theme in the SCLogin module settings area. If you're using multiple templates, you'll need a copy in the default folder and then another copy of those files in any templates you may assign to pages of your site.
I hope that helps, but if you need anything else, please let us know.
Thanks,
Alex
