KmlLayer may not consistently appear on the screen

My website features a Google V3 API map with four KML layers added to it. However, I've noticed that sometimes only two or three layers load, with the last one being the least frequent.

When refreshing the page, more layers seem to load. Below is the javascript code I'm using:

function initializeGoogleMap() 
{
    var mapOptions = {
            center: { lat: 45.325, lng: 14.254},
            zoom: 12,
            panControl: false,
            zoomControl: false,
            mapTypeControl: true,
            scaleControl: false,
            streetViewControl: false,
            overviewMapControl: false,
            mapTypeId: google.maps.MapTypeId.HYBRID
        };
    map = new google.maps.Map(document.getElementById('map-canvas'),mapOptions);
    
    new google.maps.KmlLayer({url:"https://www.virtualmountains.co.uk/Istria/PlacesOPOV1c.kml",map: map, preserveViewport: true});
    new google.maps.KmlLayer({url:"https://www.virtualmountains.co.uk/Istria/RoutesEdgeV1k.kml",map: map,preserveViewport: true});
    new google.maps.KmlLayer({url:"https://www.virtualmountains.co.uk/Istria/RoutesFillV1k.kml",map: map,preserveViewport: true});
    new google.maps.KmlLayer({url:"https://www.virtualmountains.co.uk/Istria/RoutesOPOV1n.kml",map: map,preserveViewport: true});
}

It seems that the KML files may be taking too long to download, causing them not to be available in time for mapping.

Any suggestions on how to address this issue?

To provide clarity, here is the ultimate solution

function initializeGoogleMap() 
{
    var mapOptions = {
            center: { lat: 40.7128, lng: -74.0060},
            zoom: 10,
            panControl: true,
            zoomControl: true,
            mapTypeControl: false,
            scaleControl: true,
            streetViewControl: true,
            overviewMapControl: true,
            mapTypeId: google.maps.MapTypeId.TERRAIN
        };
    map = new google.maps.Map(document.getElementById('map-canvas'),mapOptions);
        
    new google.maps.KmlLayer({url:"https://www.uniqueadventures.com/Nature/TrailsA1.kml", map: map, zIndex: 0, preserveViewport: true});
    new google.maps.KmlLayer({url:"https://www.uniqueadventures.com/Nature/TrailsB1.kml", map: map, zIndex: 1, preserveViewport: true});
    new google.maps.KmlLayer({url:"https://www.uniqueadventures.com/Nature/TrailsC1.kml", map: map, zIndex: 2, preserveViewport: true});
    new google.maps.KmlLayer({url:"https://www.uniqueadventures.com/Nature/TrailsD1.kml", map: map, zIndex: 3, preserveViewport: true});
    
}
