Select-ui removes model object from select options in some versions - angularjs

Question

I have a list of objects that I iterate in the repeat attribute of ui-select.
I bind in the model one of these objects and then it disappears from the select options.
Html-Snippet
<div ui-select="" data-ng-disabled="" data-ng-model="selectedPerson">
<div ui-select-match="" placeholder="Select">
<div>
<span>{{$select.selected.name}}</span>
</div>
</div>
<div ui-select-choices="" data-repeat="person in people" data-scrollable="">
<div>
<span class="itembalance">{{person.name}}</span>
</div>
</div>
</div>
Js-Controller
app.controller('DemoCtrl', function($scope, $http, $timeout) {
$scope.people = [
{ name: 'Adam', email: 'adam#email.com', age: 12, country: 'United States' },
{ name: 'Amalie', email: 'amalie#email.com', age: 12, country: 'Argentina' },
{ name: 'Estefanía', email: 'estefania#email.com', age: 21, country: 'Argentina' },
{ name: 'Adrian', email: 'adrian#email.com', age: 21, country: 'Ecuador' },
{ name: 'Wladimir', email: 'wladimir#email.com', age: 30, country: 'Ecuador' },
{ name: 'Samantha', email: 'samantha#email.com', age: 30, country: 'United States' },
{ name: 'Nicole', email: 'nicole#email.com', age: 43, country: 'Colombia' },
{ name: 'Natasha', email: 'natasha#email.com', age: 54, country: 'Ecuador' },
{ name: 'Michael', email: 'michael#email.com', age: 15, country: 'Colombia' },
{ name: 'Nicolás', email: 'nicolas#email.com', age: 43, country: 'Colombia' }
];
$scope.selectedPerson = { name: 'Wladimir', email: 'wladimir#email.com', age: 30, country: 'Ecuador' };
});

Any idea what is wrong. This started happening after I upgraded to this version. It does not occur with 0.7.* I could not find any changelog that indicated the reason for this.
Target version is 0.17.1

Answer 1

This might be a bug about ui-select. If you set the value after directive is compiled, then there is no problem
$timeout(function() {
$scope.select.selectedPerson = $scope.people[1];
}, 2000);

But if you set the default value before it is compiled, then option is removed.

Ok, worked around it and compared the two versions 0.17.1 and 0.18.0
Seems some changes have been done in both. I did not dig too much but setting remover-selected="false" seems to solve the problem. in 0.17.1 this version was set by default to false though now is is set based on uiSelectConfig.
<div ui-select="" data-ng-disabled="" data-ng-model="selectedPerson" remove-selected="false">
Anyone else stumbles upon this, I would recommend going with 0.17.1 though which is mostly the same.
