Answer 1

It looks like whatever library you're using for the mwlCalendarPreviousView and mwlCalendarNextViewdirectives and mwl-calendar-month-view component is not present/imported correctly.

The example link you provided has a link to this StackBlitz. Looking at module.ts, there are several module imports present that are missing from your app.module.ts. Since you're having issues with the calendar, I think you need to add this import

@NgModule({
  imports: [
    CommonModule,
    FormsModule,
    NgbModalModule.forRoot(),
    FlatpickrModule.forRoot(),
    CalendarModule.forRoot() <---- This One
  ],
  declarations: [DemoComponent],
  exports: [DemoComponent]
})
export class DemoModule {}
