like below fixes the issue You have to handle it with an array of selected address'es. This would be like so - where selectedAddress is an array:
code :
<div *ngFor="let person of persons; let i = index">
  <select [ngModel]="selectedAddress[i]" (ngModelChange)="selectedAddress[i] = $event">
    <option *ngFor="let address of person.addresses" [ngValue]="address">
        {{address.type}}
    </option>
  </select>
  <textarea [(ngModel)]="selectedAddress[i].address"></textarea>
</div>

Angular ng-model bound from nested ng-repeat

I wish this help you You would be better off using the ng-options directive with the select directive. Using select + ngRepeat has all sort of limitations and is better avoided. Is there any particular reason for generating options with ngRepeat?
If you could share more code (especially the structure of your data model) I might be able to provide more info.

around this issue Ok ok ok, I've found the problem!!
Like I says, it is a POC and I did this quick. The problem come from the «Aptitudes» array that I have defined... and reused for every employee defined in the array...
code :
self.aptitudes= [
    { id: 1, title: 'Aptitude 1', value: 0 },
    { id: 2, title: 'Aptitude 2', value: 0 },
    { id: 3, title: 'Aptitude 3', value: 0 }   
];

// Mock data...
self.employees = [
    { id: 1, firstName: 'FirstName1', lastName: 'LastName1', photo: 'img/photo1.png', grade: 0, aptitudes: self.aptitudes, displayAptitudes: false },
    { id: 2, firstName: 'FirstName2', lastName: 'LastName2', photo: 'img/photo2.png', grade: 0, aptitudes: self.aptitudes, displayAptitudes: false }
];
function getAptitudes() {
    return [
        { id: 1, title: 'Aptitude 1', value: 0 },
        { id: 2, title: 'Aptitude 2', value: 0 },
        { id: 3, title: 'Aptitude 3', value: 0 }   
    ];
}

will help you Instead of using [value] in your select, use name:
So the following
code :
<select class="form-control" formControlName="phoneType">
  <option [value]="home" title="For home phone">HOME</option>
  <option [value]="sms" title="For text messaging">SMS</option>
  <option [value]="tty" title="For the deaf">TTY</option>
</select>
<select class="form-control" formControlName="phoneType">
   <option name="home" title="For home phone">HOME</option>
   <option name="sms" title="For text messaging">SMS</option>
   <option name="tty" title="For the deaf">TTY</option>
</select>
