why QIterator object behave differently for same folder placed in two different locations?

I have a folder inside which i have following folder(s)/file(s) (Folder in bold)

1.make_file_example

1.1.main.cpp
1.2.MakeFile
1.3.message.cpp
1.4.message.h

2.makeFileExample.txt
3.other_sources.txt
4.QTnotes.txt

[I've copy/pasted the same folder in two different locations] In following images you can clearly see how same folder when placed in different location give different results

the code snippet I've used is as follows:

   void MainWindow::on_pushButton_browse_clicked()
{
    ui->textBrowser_filename->setLineWrapMode(QTextEdit::NoWrap);
    ui->textBrowser_filename->setText("");
    QString dir= QFileDialog::getExistingDirectory(this, tr("Open Directory"),
                                                   "/home",
                                                   QFileDialog::ShowDirsOnly
                                                   | QFileDialog::DontResolveSymlinks);
    ui->lineEdit_dir->setText(dir);
    QDirIterator it(dir, QDir::NoDotAndDotDot | QDir::AllEntries , QDirIterator::Subdirectories | QDirIterator::FollowSymlinks);
    while(it.hasNext())
    {
        QString path=it.fileName();
        ui->textBrowser_filename->append(path);
        it.next();
    }
}
