adal.init duplicates app-root

[Terriuss]

When using adal.init (for example in the app.compontent.ts) the app-root gets duplicated (see screenshot). (Removing the line adal.init solves the duplicating issue)

import { Component, OnInit } from '@angular/core';
import { AdalService } from 'adal-angular4';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent{
  title = 'TestApp';
  private adalConfig ={
    tenant: 'XXXX',
    clientId: 'XXXX',
    redirectUri: 'http://localhost:4200/',
    postLogoutRedirectUri: 'http://localhost:4200/'
  }
  constructor(private adal : AdalService){
    this.adal.init(this.adalConfig);
  }
}

What does your app.component.html look like? Perhaps you have <router-outlet> inserted twice?
