<ion-item>
              <ion-label position="floating" color="primary">License</ion-label>
              <ion-select [(ngModel)]="license.id" formControlName="selectedlicense">
                <ion-select-option *ngFor="let lic of licenses" [value]="lic.id">{{lic.title}}</ion-select-option>
              </ion-select>
            </ion-item>

licenses = [
        {id: 1, title: 'test123'}
    ]
    license = {
        id: 1
    }

ion-select does not select the the active item if the model is a number
if you change the ion-select model from 1 to '1' (string) all is working fine

license = {
        id: '1'
    }
