dockmanager savesate only save the layout of first dock area

[BarryArch]

I want to save the dock layout to a file and reload it when reopen.
the code of save dock layout :

    QFile file("VisualLayout.ini");
	if (file.open(QIODevice::WriteOnly))
	{
		QDataStream out(&file);
		out << _dockMan->saveState();
		file.close();
	}

and the code of load the config file:

 QFile file("VisualLayout.ini");
	if (file.open(QIODevice::ReadOnly))
	{
		QByteArray ba;
		QDataStream in(&file);
		in >> ba;
		file.close();
        
		if (_dockMan->restoreState(ba))
		{
			qDebug() << QString("good");
		}
		else
		{
			qDebug() << QString("failed");
		}
	}

but it just reload the 1st dock area layout, and totally ignored other dock area.

Not sure which is the official repo, but https://github.com/githubuser0xFFFF/Qt-Advanced-Docking-System is staying up to date. @BarryArch you may find better luck with that other repo.
