Mapbox Cluster does not split into individual markers when zooming

everyone. I want to show a cluster using mapbox. I get it to the point where I can see the number of markers within a cluster. However, if I zoom into the map, the display does not change to where I see individual markers on the map. See image. I use the following lib for the mapbox for React: https://visgl.github.io/react-map-gl/docs/api-reference/map . Thank you very much

useEffect(() => {
const points = alleArtikel.map((artikel) => ({
  type: "Feature",
  properties: {
    cluster: false,
    artikelId: artikel._id,
    name: artikel.name,
    beschreibung: artikel.beschreibung,
    lng: artikel.long,
    lat: artikel.lat,
    bild: artikel.bild,
    userId: artikel.userId,
  },
  geometry: {
    type: "Point",
    coordinates: [parseFloat(artikel.long), parseFloat(artikel.lat)],
  },
}));
setPoints(points);
}, [alleArtikel]);

useEffect(() => {
supercluster.load(points);
setClusters(supercluster.getClusters(bounds, zoom));
}, [points, zoom, bounds]);

useEffect(() => {
if (mapRef.current) {
  setBounds(mapRef.current.getMap().getBounds().toArray().flat());
}
}, [mapRef?.current]);


         {clusters?.map((artikel) => {
          const { cluster: isCluster, point_count } = artikel.properties;
          const [longitude, latitude] = artikel.geometry.coordinates;
          if (isCluster) {
            return (
              <Marker
                key={artikel.id}
                longitude={longitude}
                latitude={latitude}
                onClick={() => setShowPopup(true)}
              >
                <div
                  className="cluster-marker"
                  style={{
                    width: `${13 + (point_count / points.length) * 20}px`,
                    height: `${13 + (point_count / points.length) * 20}px`,
                  }}
                  onClick={() => {
                    const zoom = Math.min(
                      supercluster.getClusterExpansionZoom(artikel.id),
                      10
                    );
                    mapRef?.current.flyTo({
                      center: [longitude, latitude],
                      zoom,
                      speed: 1,
                    });
                  }}
                >
                  {point_count}
                </div>
              </Marker>
            );
          }

          return (
            <Marker

                </Tooltip>

                {showPopup && (
                  <Popup
                    closeOnClick={false}
                    closeButton={true}

                      <Box>
                        <Typography variant="body1" align="center">

                      <Box>
                        <Button variant="contained" fullWidth>

              </Box>
            </Marker>
          );
        })}

This is what the map looks like when it is initially loaded

If I zoom in very closely, the point does not change or split
