[SOLVED] Lazy Loading BrowserModule has already been loaded

I am trying to implement lazy loading but getting error as following **

ERROR Error: Uncaught (in promise): 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.

Need Help on this. Here are my Modules

Shared MOdule

@NgModule({

  declarations: [TimePipe],
  providers: [
    EmsEmployeeService,
    EmsDesignationService,
    EmsOrganizationService,
    EmsAuthService,
    AmsEmployeeService,
    AmsShiftService,
    ValidatorService,
    AmsLeaveService,
    AmsAttendanceService,
    AmsDeviceService,
    AmsOrganizationService,
    AmsAlertService,
    AmsHolidayService,
    AutoCompleteService,
    AmsTimelogsService,
    LocalStorageService
  ],
  imports: [
    HttpModule,
    ToastyModule.forRoot(),
    AgmCoreModule.forRoot({
      apiKey: 'xxxxxxxxxxxxxxxxxxxxxxxxxxx'
    }),
  ],
  exports: [
    FormsModule,
    HttpModule,
    BrowserAnimationsModule,
    RouterModule,
    MaterialModule,
    MdDatepickerModule,
    MdNativeDateModule,
    ToastyModule,
    FileUploadModule,
    NgxPaginationModule,
    NguiAutoCompleteModule,
    AgmCoreModule,
    TimePipe
  ]
})
export class SharedModule { }

2.SettingModule

 @NgModule({
  imports: [
    CommonModule,
    SharedModule,
    SettingsRoutingModule
  ],
  declarations: [
    SettingsComponent,
    ShiftsComponent,
    DevicesComponent,
    AlertsComponent,
    HolidaysComponent,
    AlterTypesComponent,
    AlterEditComponent,
    ShiftTypeNewComponent,
    DeviceLogsComponent,
    ChannelTypesComponent,
    ChannelTypeEditComponent
  ], exports: [
    SettingsComponent,
    ShiftsComponent,
    DevicesComponent,
    AlertsComponent,
    HolidaysComponent,
    AlterTypesComponent,
    AlterEditComponent,
    ShiftTypeNewComponent,
    DeviceLogsComponent,
    ChannelTypesComponent,
    ChannelTypeEditComponent,
  ]
})
export class SettingsModule { }

3.SettingRoutingModule
