我使用 objectManager 在地图上显示标记。单击时未打开单个标签的气球。单击分组气球时，它会正常显示。这是地图调用：

var myMap,
    geoObjects,
    objectManager,
    arr_check = [];

ymaps.ready(init);
        function init()
        {
            myMap = new ymaps.Map('map', {
                    center: [".$last_gps."],
                    zoom: 14,
                    type: 'yandex#satellite'
                }, {
                    searchControlProvider: 'yandex#search'

                });
                objectManager = new ymaps.ObjectManager({
                    clusterize: true,
                    gridSize: 32,
                    clusterDisableClickZoom: true
                });
                objectManager.objects.options.set('preset', 'islands#grayDotIcon');
                objectManager.clusters.options.set('preset', 'islands#grayClusterIcons');
                myMap.geoObjects.add(objectManager);

                $.ajax({
                    url: 'panel_json.php',
                    type: 'post',
                    dataType: 'json',
                    data: {arrp:arr_check}
                }).done(function(data) {
                    objectManager.add(data);
                    geoObjects = ymaps.geoQuery(data)
                            .applyBoundsToMap(myMap, {
                                checkZoomRange: true
                            });
                });

                myMap.geoObjects.add(objectManager);

        };

我接受这样的 JSON：

{
"type": "FeatureCollection",
"features": [
    {
        "type": "Feature",
        "geometry": {
            "type": "Point",
            "coordinates": "55.831903, 37.411961"
        },
        "properties": {
            "balloonContent": "<a href=\'more.php?id=1\'>Описание</a>",
            "hintContent": "Описание",
            "clusterCaption": "Описание"
        },
        "options": {
            "preset": "islands#icon",
            "iconColor": "#00AA00"
        }
    }
]

}
