Left hand border missing in modals

[PeterSawyer]

Slight issue with the switch in a modal. Left hand border missing. See attached image.

Am using the angular-modal-service.

Any ideas?

View markup is as per: -

<div class="modal fade">
    <div class="modal-dialog modal-lg">
        <div class="modal-content">

            <form name="formAgencyPost" class="form-horizontal" role="form">

                <div class="modal-header">
                    <button type="button" class="close" ng-click="close()" data-dismiss="modal" aria-hidden="true">&times;</button>
                    <h4 class="modal-title">{{ title }}</h4>
                </div>

                <div class="modal-body">

                    <div class="form-group">
                        <label for="testSwitch" class="control-label col-sm-4 col-lg-3">Test switch</label>
                        <div class="col-sm-8 col-lg-6">
                            <toggle-switch id="testSwitch"
                                name="testSwitch"
                                data-model="testSwitch"
                                class="switch-success"
                                on-label="true"
                                off-label="false"
                                required="required">
                            </toggle-switch>
                        </div>
                    </div>

                </div>

                <div class="modal-footer">
                    <button type="submit" ng-click="close()" class="btn btn-primary">OK</button>
                    <button type="button" ng-click="cancel()" class="btn btn-default">Cancel</button>
                </div>

            </form>

        </div>
    </div>
</div>

I got rid of the large columns and it worked.

ie. removed col-lg-3 from the label and col-lg-6 from the div
