Why doesn't Nested Set work in Yii2?

Question

MySQL

The table has columns for the Nested Set

. As logic, the ready-made module
https://github.com/creocoder/yii2-nested-sets
is used to build a tree and drag and drop is used
https://github.com/wbraganca/yii2-fancytree -widget
The data for it forms
https://github.com/wokster/yii2-nested-sets-tree-b...
Everything is connected, everything moves, but in the base the lft rgt and depth values ​​are not updated correctly for the depth value even with a minus get
the code:

<?= \wbraganca\fancytree\FancytreeWidget::widget([
  'options' =>[
    'source' => $data,
    'extensions' => ['dnd'],
    'dnd' => [
      'preventVoidMoves' => true,
      'preventRecursiveMoves' => true,
      'autoExpandMS' => 400,
      
      'dragStart' => new JsExpression('function(node, data) {
        return true;
      }'),
      'dragEnter' => new JsExpression('function(node, data) {
        return true;
      }'),
      'dragDrop' => new JsExpression('function(node, data) {
        $.get("move",{item: data.otherNode.data["id"], action: data.hitMode, second: node.data["id"]},function(e ) {
          data.otherNode.moveTo(node, data.hitMode);
          console.log(e);
        });
      }'),
    ],
  ]
]);
?>

public function actionMove($item,$action,$second)
    {
    $item_model = $this->findModel($item);
    $second_model = $this->findModel($second);
    
    switch($action) {
      case 'after':
        $item_model->insertAfter($second_model);
        break;
      case 'before':
        $item_model->insertBefore($second_model);
        break;
      case 'over':
        $item_model->appendTo($second_model);
        break;
    }
    if($item_model->save()) {
      return print_r($item_model);
    }
    return true;
    
    }

when moving, ajax is triggered and the data is correct

. Visually, everything works and the data arrives correctly on the creocoder functions, but the changes are not correct. What to do? Is it just me or do others have problems too?

Probably validation, make lft rgt and depth safe attributes

return [
....
[['lft','rgt','depth'],'safe'],
....
];
