Toggle blank list

Hello

Why when I use toggle I get blank item

<ion-list >

    <ion-item-sliding *ngFor="let expense of expenses; let i=index">
      <ion-item nopadding >
          <p item-start>
              {{i+1}}
          </p>

        <div>
        <div>
          <!--{{expense.rowid}}<br>-->
          {{expense.description}} <br>
          <div *ngIf="expense.paid == 'YES'">
            <label  >Paid: </label>
            <ion-icon style="color:green" name="checkmark-circle-outline"></ion-icon><br>
          </div>
          Starting: {{expense.date | date: 'dd/MM/yyyy HH:mm'}}<br>
          Type: {{expense.type}}<br>
          Recurring: {{expense.recurring}}<br>
          <label *ngIf="expense.recurring =='Monthly'; else weekly">Every {{expense.date | date: 'dd'}} of Month at {{expense.date | date: 'HH:mm'}} </label>

          <label >Added: {{expense.added_date | date: 'dd/MM/yyyy HH:mm'}}</label> <br>
          <div *ngIf="expense.today_pay == 'YES' && !expense.paid">
            <label  >Today Payment: </label>
            <ion-icon  style="color:green" name="checkmark-circle-outline"></ion-icon><br>
            <ion-icon name="information-circle"></ion-icon>
            <label>Swipe left to marked it as paid</label>
                <ion-label>Test</ion-label>
                <ion-toggle [(ngModel)]="test"></ion-toggle>
          </div>
