How do I hide labels in styled map of Philipines?

Question

I have the problem with Philipines`s view at map:

Map styles:

     var styles = [
           {"stylers": [{ "visibility": "off" }]},
           {
               "featureType": "administrative",
               "elementType": "geometry.stroke",
               "stylers": [
                   {
                       "visibility": "on"
                   },
                   {
                       "color": "#ffffff"
                   },
                   {
                       "weight": 1
                   }
               ]
           },
           {
                featureType: "administrative.province",
                elementType: "geometry",
                stylers: [
                    { visibility: "off" }
                ]
           },
           {
               featureType: "administrative.country",
               elementType: "labels",
               stylers: [
                   { visibility: "off" }
               ]
           },
           {
               "featureType": "landscape",
               "elementType": "all",
               "stylers": [
                   {
                       "visibility": "on"
                   },
                   {
                       "color": "#a2d39c"
                   }
               ]
           },
           {
               "featureType": "water",
               "elementType": "all",
               "stylers": [
                   {
                       "visibility": "on"
                   },
                   {
                       "color": "#0e76bc"
                   }
               ]
           }
       ];

All fine,except Philipines with strange "titles" on it. I haven`t any ideas...
