Pagination on ionic modal displayed only for first time, next is open only the modal whitout pagination

Ionic Framework ionic-v3
1

I have this code :

markerClick(params: any) {
    const marker: Marker = params[1] as Marker;
    marker.hideInfoWindow();
    this.service.getList().then(async (liste: any) => {
        const modal = await this.modalController.create({
            component: ModalComponent,
            cssClass: 'map-modal',
            componentProps: {
                liste
            }
        });
        return await modal.present();
    });
}

and my modal component

export class ModalComponent implements OnInit {

@Input() campaigns;

slideOpts = {
    slidesPerView: 1,
    paginationType: 'fraction'
};

ngOnInit() {

}

constructor(
    public navParams: NavParams,
    public modalController: ModalController
    ) {
    this.liste = navParams.get('liste');
}

closeModal() {
    this.modalController.dismiss();
}

}

The html of modal :

<ion-header>
<ion-toolbar>
    <ion-buttons slot="end">
        <ion-icon icon="close" (click)="closeModal()">Close</ion-icon>
    </ion-buttons>
</ion-toolbar>
</ion-header>
<ion-content>
<ion-slides pager="true" [options]="slideOpts">
    <ion-slide *ngFor="let list of liste">
        <liste-app
                [list]="list"
        ></liste-app>
    </ion-slide>
</ion-slides>

The paginations is displayed only the first time when I open the modal, and I can navigate with swipe between sliders. WHen I open next times the paginations dissaper and I can’t navigate swipe mode. Very strange behaviour. I need to refresh the browser and after that will work, only for the first time. Have you an idea about that ? Thx in advance and sorry for my english. Any ideas ?
