ngDupes error with the checkboxes AngularJs

I'm trying to fix my ngdupes error with the checkbox selection. I don't know what's going wrong. Can someone please help? Here is my code:

$scope.GetMultiCheckBox = function GetMultiCheckBox(CheckBoxs) {
            var idx = $scope.selectedfunction.indexOf(CheckBoxs);
            if (idx > -1) {
                  $scope.selectedfunction.splice(idx, 1);
            }

            else {
                  $scope.selectedfunction.push(CheckBoxs);

            }
      };
    $scope.FilterValueByFunction = function (FunctionVal) {
            $scope.Lv7 = [];

            if (!$scope.selectedfunction.length == '') {


                  for (var i = 0; i < $scope.LoadAllData.length; i++) {

                        for (var j = 0; j < $scope.selectedfunction.length; j++) 
     {
                              if($scope.LoadAllData[i].Business_x0020_Checkbox.results.toString().match($scope.selectedfunction[j])) {
                                    $scope.Lv7.push($scope.LoadAllData[i]);
                              }
                        }
                  }


            } else {
                  for (var i = 0; i < $scope.LoadAllData.length; i++) {

                        $scope.Lv7.push($scope.LoadAllData[i]);
                  }
            }


      };

Here is my HTML code:

<input id="" type="checkbox" value="" ng-disabled="Site.length == 0" ng-checked="selectedFunction.indexOf(item) > -1"
                                    ng-click="GetMultiCheckBox(item); FilterValueByFunction(item);" autocomplete="off"/>

Thanks!
