Rollup including my react library into bundle even though I have externals written

I am trying to build a component library for myself with a few overrides. But it's constantly giving me an insane challenge. I can't import it into my projects. Rollup for some reason is packing the whole react lib into my bundle.js file.

This rollup config

/* eslint-disable */
import { readdirSync } from 'fs';
import path from 'path';
import babel from 'rollup-plugin-babel';
import commonjs from 'rollup-plugin-commonjs';
import external from 'rollup-plugin-peer-deps-external';
import replace from 'rollup-plugin-replace';
import resolve from 'rollup-plugin-node-resolve';
import postcss from 'rollup-plugin-postcss';
import { terser } from 'rollup-plugin-terser';
import pkg from './package.json';

const EXTENSIONS = ['.ts', '.tsx', '.js', '.jsx', '.json'];
const CODES = [
  'THIS_IS_UNDEFINED',
  'MISSING_GLOBAL_NAME',
  'CIRCULAR_DEPENDENCY'
];

const discardWarning = (warning) => {
  if (CODES.includes(warning.code)) {
    return;
  }

  console.error(warning);
};

const env = process.env.NODE_ENV;

const commonPlugins = () => [
  postcss({
    extract: true,
    modules: true,
    use: ['sass']
  }),
  external(),
  babel({
    babelrc: false,
    presets: [['@babel/preset-env', { modules: false }], '@babel/preset-react'],
    extensions: EXTENSIONS,
    exclude: [
      'node_modules/**',
      'src/*/*.stories.js',
      'src/*/*.spec.js',
      'src/*/*.test.js'
    ]
  }),
  commonjs({
    include: /node_modules/
  }),
  replace({ 'process.env.NODE_ENV': JSON.stringify(env) }),
  resolve()
];

export default [
  {
    onwarn: discardWarning,
    input: 'src/index.js',
    output: {
      esModule: false,
      file: pkg.unpkg,
      format: 'cjs',
      name: 'ph-shared',
      exports: 'named'
      globals: {
        antd: 'antd',
        react: 'React',
        'react-dom': 'ReactDOM'
      }
    },
    external: ['react', '@ant-design', 'react-notification-system', 'antd'],
    plugins: [...commonPlugins(), env === 'production' && terser()],
    output: [{ dir: 'dist', format: 'cjs', exports: 'named', sourcemap: true }]
  }
];

and this is package.json file

I also want to override some antD styles using SCSS. and it's converting all the classes with funny names even though they are not scss modules. It's extracting out a single file with all of my classes renamed. I was expecting only scss modules classes to be renamed.
