When using exported configuration it is important to remove the UUID from the configuration. Every piece of configuration is uniquely identified by this ID. If you would include this UUID in your module the ID would be the same for all sites that use your module, so it would not be unique any more. If you simply remove this line from the configuration Drupal will generate new UUIDs when your module is enabled, guaranteeing uniqueness.
