Using Ng-select clearable for only one field

The following code is for two filters. However, when you click the clear button in one of the filters, both filters get cleared. Is there a way to use the [clearable] property so that only the clicked filter gets cleared?

<div class="filter-item" *ngFor="let datum of data" [ngClass]="{'select-filter': selectedItem && selectedItem?.label}'>

  <div class="title">
    <span>{{ datum.key }}</span>
  </div>

  <div class="select">
    <ng-select #select [placeholder]="'Select'" [items]="datum.data" [multiple]="false" 
     bindLabel="label" [(ngModel)]="datum.selectedItems" appendTo="body" 
     (change)="onChange($event, datum)">
    </ng-select>
  </div>

</div>
