I can't see the Monthly, Weekly, Day, List View mode button.

[UngKaKu]

<FullCalendar
initialView="dayGridMonth"
header={{
left: "prev,next today",
center: "title",
right: "dayGridMonth,timeGridWeek,timeGridDay,listWeek"
}}
rerenderDelay={10}
eventDurationEditable={false}
editable={true}
droppable={true}
plugins={[
dayGridPlugin,
timeGridPlugin,
interactionPlugin,
]}
ref={this.calendarComponentRef}
weekends={this.state.calendarWeekends}
events={this.state.calendarEvents}
eventDrop={this.drop}
// drop={this.drop}
eventReceive={this.eventReceive}
eventClick={this.eventClick}
// selectable={true}
/>

this is my code.

How can I display all of those button properly?
