Lower part of the tree vanishes when expanding parents node

[aespogom]

I have a deep tree with at maximum 5 levels in Angular 13. When the nodes are loaded, the preview is fine. However, the problem is that if I try to expand level 3 to a hidden level 4, the lower part is the tree (level 1 and 2) disappears!

This image is the preview right after loading the nodes:

These are my nodes: `

This is my FamilyTree configuration summarized: `

    const tree = document.getElementById('tree');
    if (tree) {
          var chart = new FamilyTree(tree, {
              template: 'john',
              orderBy: "birthday" ,
              lazyLoading: true,
              mouseScrool: FamilyTree.action.ctrlZoom,
              orientation: FamilyTree.orientation.top,
              editForm: {...}
              nodeMenu: {},
              nodeContextMenu: {},
              menu: {},
              nodeCircleMenu: {},
              scaleInitial: FamilyTree.match.boundary,
              nodeBinding: {...}
          });
    }
    chart.load(nodes);

` This is what happens when clicking on the parent node from the previous image: The nodes from level 3 and 4 are right but level 1 and 2 disappears.

These are the versions I am using: "@balkangraph/familytree.js": "^1.7.17" Angular CLI: 13.0.4 Node: 14.18.3 Package Manager: npm 6.14.15 OS: win32 x64 Angular: 13.0.3

Thank you in advance!

The issue is that you have missed pids several times.

for example if you here pids here:

{
  id: "ececf641-f394-4b75-9d3b-58f758cc577c",
  name: "Pedro",
  pids: [
    "572505f3-cde5-460f-b078-205d4a7d53ea",
  ],
},

you should have here also

{
  id: "572505f3-cde5-460f-b078-205d4a7d53ea",
  name: "Lola",
  pids: [
    "ececf641-f394-4b75-9d3b-58f758cc577c",
  ],
},

You are totally right!! I did not notice that I was missing some pids. Thank you so much for your help.
