ArcGIS Javascript adding an extra row to featurereduction popup

geoJSONLayer.featureReduction = {

Does your PopupTemplate have a title property? If it doesn't, you get this "Untitled" text for the summary row. You can review this sample to help.

That syntax was very annoying.. It was counting the summary and it makes it appear as if there were an additional feature in the scroll. I ended up bypassing the browse features button with view.popup.open for the cluster features and the popup template for the single points!

view.on("click", async (event) => {
          const layerView = await view.whenLayerView(geoJSONLayer);
          const response = await view.hitTest(event, { include: geoJSONLayer });
          console.log(response);
          const cluster = response.results[0].graphic;
      
          const id = cluster.getObjectId();
          const q = layerView.createQuery();
          q.aggregateIds = [id];
          const { features } = await layerView.queryFeatures(q);
          //console.log(features.results[0]);
          if (features.length === 0) {
            geoJSONLayer.popupTemplate = template;
          } else {
            view.popup.open({ features });
          }
          
        });

 Here's the code to how I solved it!
