映射标记标签，过滤后显示方式不同

Question

我正在使用Google地图。根据服务过滤地图后出现的问题。它显示了不同的标记标签。

这是我的产品链接 https://cdn.assetrepository.me/maps-test/

the image is after filter

here is the images showing marker

这是我用于过滤Google Maps标记的代码。

$('input[name="showroom_services"]').on("change", function(){
    markerCluster.clearMarkers();
    markers = [];
    var searchField = $('#showroom_search').val();
    var expression = new RegExp(searchField, "i");
    var listfilterW=[];
    var markerAlreadyMade=[];
    $('input[name="showroom_services"]').each(function(){
        if($(this).prop("checked")==true) {
            let crRef=$(this);
            $.each(jsondata, function(key, value) {

                if(value.city.search(expression) !== -1){

                    if(value['services_list'].indexOf($(crRef).val()) !== -1)
                        if(markerAlreadyMade.indexOf(value.dealerId)==-1)
                        {

                        //   console.log(value.['services_list'])
                            // if(value.city.search(expression) !== -1){
                                listfilterW.push(value);
                                markerAlreadyMade.push(value.dealerId)
                        }
                }
            });
        }
    })

    if(listfilterW.length > 0){
        $.each(listfilterW, function(key, value) {
            drawMarkers(value, "null");
        });
    }else{
        $.each(alldata, function(key, value) {
            drawMarkers(value, "null");
        });
    }
    $('.reset_filter').click(function(){
        if(listfilterW.length > 0){
            $('.dealer-item.list_active').removeClass('list_active');
            markerCluster.clearMarkers();
            markers = [];
        }
    });
});
