Why is the select selection left empty?

Question

Angular

TS:

ngOnInit() {
        this.route.data
            .subscribe(data => {
                    console.log(data);
                    var params = data['params'];
                    this.car_brands = params['car_brands'];
                    this.car_classes = params['car_classes'];
                    this.taxi_brands = params['taxi_brands'];
                    this.client_types = params['client_types'];
                    this.tariffs = params['group_tariffs'];
                    Object.assign(this.model, data['data']);
                    console.log(data);
                },
                error => {
                    console.log(error['error']);
                    this.errors = error['error'];
                });
    }

HTML:

<div [ngClass]="hasError('number')" class="form-group">
        <label class="col-lg-3 control-label">Номер:</label>
        <div class="col-lg-9">
          <input type="text" class="form-control" [(ngModel)]="model.number" name="number">
          <span *ngIf="errors['number']" class="help-block">{{errors['number'][0]}}</span>
        </div>
      </div>

      <div [ngClass]="hasError('brand_id')" class="form-group">
        <label class="col-lg-3 control-label">Бренд такси:</label>
        <div class="col-lg-9">
          <select name="repeatSelect" id="repeatSelect" class="form-control"  [(ngModel)]="model.brand_id" >
            <option *ngFor="let item of taxi_brands;" [value]="item['id']"> {{item.name}} </option>
          </select>
          <span *ngIf="errors['brand_id']" class="help-block">{{errors['brand_id'][0]}}</span>
        </div>
      </div>

In the TS code, I fill in the array for select, then the model itself, I use a simple one, without formcontrols, then in html the input and radio buttons are filled, and the selection decreases for selects. on other pages everything is ok, but there I use an array of arrays, and here an array of objects, and my selection drops ...
