Can´t include breadcrumb in feature module

[dominikampletzer]

I try to include the breadcrumb in a feature module. not in the root/app module.

if i import BreadcrumbsModule and use it as discribed
<breadcrumb [allowBootstrap]="true"></breadcrumb> in my headerModule
i get the Error: BrowserModule has already been loaded. If you need access to common directives such as NgIf and NgFor from a lazy loaded module, import CommonModule instead.

But BrowserModule is only imported in my Root/App module. the feature module - headerModule- imports Common Module

app.module.ts
`import {NgModule} from '@angular/core';
import {BrowserModule} from '@angular/platform-browser';
import {AppComponent} from './app.component';
import {AppRoutingModule} from "./app-routing.module";
import {NgbModule} from "@ng-bootstrap/ng-bootstrap";
import 'bootstrap/dist/css/bootstrap.min.css';

@NgModule({
imports: [
AppRoutingModule,
BrowserModule,
NgbModule.forRoot(),
],

declarations: [
    AppComponent,
],
providers: [],
bootstrap: [
    AppComponent,
],

})
export class AppModule {
}
`

header.module.ts
`import {NgModule} from '@angular/core';
import {CommonModule} from '@angular/common';
import {HeaderRoutingModule} from "./header-routing.module";
import {HeaderComponent} from "./header.component";
import {BreadcrumbsModule} from "ng2-breadcrumbs";

@NgModule({
imports: [
CommonModule,
HeaderRoutingModule,
BreadcrumbsModule
],
declarations: [
HeaderComponent,
],
exports: [
HeaderComponent,
],

})
export class HeaderModule {
}
header.component.tsimport {Component} from '@angular/core';
@component({
selector: 'pp-header',
template: <div class="header-container"> <div class="breadCrumb"> <breadcrumb [allowBootstrap]="true"></breadcrumb> </div> </div>,
styleUrls: [String('../../styles.css'), String('./header.css')]
})

export class HeaderComponent {}
`

Any solution for this behavior? I am in the same situation.

This still doesn't work -- now with ng6-breadcrumb. Cannot import into any module besides app.module it would seem.
