Ordering table data from separate JSON file by using AngularJS

Question

I'm trying to sort the data in the units section alphabetically from the data that has been fetched from a JSON file. Before, I have tried to create another filter controller for the data, use GroupBy or OrderBy within the table data headers. The result I've gotten is as such where the units table disappears after any implementation of sort into the table.

The original output: here, where by the Units column should be alphabetically ordered.

I appreciate any advice given ,thank you very much!

AngularJS/appunits4.js

    var app = angular.module("myApp", []);

app.controller ("getCtrl", function ($scope, $http) {
    $http.get('data/course.json').then (
        // Successful response
        function(response) {
            $scope.course = response.data;
            $scope.status = response.status;
        },
        // Bad response
        function(response) {
            $scope.status = response.status || "File not found";
        }        
    );

use this instead of Your HTML code

 <tr class="success" data-ng-repeat="subject in course| orderBy:'Units'">
                                <td headers="code">
                                    {{subject.Codes}}
                                </td>
                                <td headers="units" >
                                    {{subject.Units}}
                                </td>
                                <td headers="credits">
                                    {{subject.Credits | number:2}}
                                </td>
                                <td headers="type">
                                    {{subject.Type}}
                                </td>
                            </tr>
