Why BUNDLE_DIR_NAME of webpack is shown wrongly ?

Question

I'd like to use webpack in Django Then, I set up like this.

WEBPACK_LOADER = {
    'DEFAULT' : {
            'BUNDLE_DIR_NAME': 'front/bundles/',
            'STATS_FILE': os.path.join(BASE_DIR, 'front/webpack-stats.json'),

    }
}

However, Request URL indicates strange URL I don't want

Taking static off in url will be perfect, How can I do this?
