I have the issue with Angular.js v1.3.11 and ng-options directive. The problem is next. I have a model value I know ahead but data for binding of options comes in Ajax request later and Angular.js produces that as two selected options: with my value and first one.

Html

  <body ng-controller="MainCtrl">
      <select ng-model="selectedYear" ng-options="o.year as o.year for o in options"></select>
  </body>

Javascript

var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope, $timeout) {
    // Known value for preselection
    $scope.selectedYear = 2013;
    $scope.options = [];

    // Ajax call emulation
    $timeout(function() {
        $scope.options = [{year: 2012}, {year: 2013}, {year: 2014}];
    });
});

Output

<select ng-model="selectedYear" ng-options="o.year as o.year for o in options" class="ng-pristine ng-valid ng-touched">
   <option value="0" selected="selected" label="2012">2012</option>
   <option value="1" selected="selected" label="2013">2013</option>
   <option value="2" label="2014">2014</option>
</select>

FWIW, it works as expected on v1.4.0-rc.1.

There's an unfortunate number of bugs in ngOptions 1.3.x. Most of them have been fixed in the 1.4.x branch, and would be very difficult to fix without breaking changes in 1.3
