Ionic 3: select one rating update them all

[ngware]

Hello, I'm using Ionic v3.19.0. I have multiple ratings on the same page. When I click on one of them, every ratings in that page take the same value. It was ok before.

Here is the html I'm using to display ratings :

<ion-item>
          <h2 text-wrap>{{q.text}} :</h2>
          <rating [(ngModel)]="q.answer"
          readOnly="false"
          max="5"
          emptyStarIconName="star-outline"
          halfStarIconName="star-half"
          starIconName="star"
          nullable="false"
          value="q.answer"
          iconOnColor= red
          iconOffColor=  red
          (ngModelChange)="selectAnswer(q, $event)"> 
        </rating>
      </ion-item>
