Checked parent - unchecked child doesn't behave correctly for decoupleChildFromParent = true

data structure:

itCategory = [new TreeviewItem({
    text: 'IT', value: 9, checked: true, children: [
      {
        text: 'Programming', value: 91, children: [], checked: false
      }
    ]
  })];

config:

    this.ngxTreeviewConfig = {
      hasAllCheckBox: false,
      hasFilter: false,
      hasCollapseExpand: true,
      decoupleChildFromParent: true,
      maxHeight: 600
    };

view:

<ngx-treeview [config]="ngxTreeviewConfig" [items]="itCategory" (selectedChange)="onSelectedChange($event)"></ngx-treeview>

results in:

should result in:

Yes, when using decoupleChildFromParent =true, any changes from parent will not reflect to children. Please change decoupleChildFromParent =false
