libraries-override not working on Drupal 8

Question

I'm trying to figure out how I can remove the default css libraries of Drupal 8 on the theme I'm working on. I tried using libraries-override: to remove a specific CSS but it doesn't seem to be working. The css file is still showing. As you can see the align.module.css is still showing on Google Network Tab. I'm not sure if the method I'm using is deprecated or incorrect
