I tried to customize bootstrap in two different ways:

In your first approach, you have customised bootstrap-3. It does not work for bootstrap-4. As far as I know, you can not customise bootstrap-4 that way. But you can do SASS files of it. For more info, visit this link
You're trying to use the Bootstrap 3 customizer for Bootstrap 4. Bootstrap doesn't offer an official customization tool for Bootstrap 4 as explained here.
You can customize with SASS, or use a tool that will build the CSS for you such as:
Bootstrap 4 customizer or Themestr.app (These are my tools)
If you're only looking to customize the Navbar color, see my answer here.
