React-native-final-tree-view : On clicking a particular node,the entire tree closes. How can I resolve this?

I'm developing a react-native app which consists of a tree view for which I have used the React-native-final-tree-view library. On clicking on a node,The entire tree closes and also the children is expanded={true} by default. How can I resolve this?

  handleNodeClick = (node,level) => {
    console.log("onPress called ", node['chapterTitle'] === undefined ? node['sectionTitle'] : node['chapterTitle']);
  }
