Root Node Text not Displaying

Greetings:

I have the following store:

Code:

Ext.define('WebApp.store.PraFolderStore',{
    extend: 'Ext.data.TreeStore',
    model: 'WebApp.model.PraFolderModel',
    storeId: 'prafolderstore',    
    lazyFill: true,
    autoLoad: false,
    proxy: {
        type: 'ajax',
        reader: 'json',
        url: '/app/data/global/Global.php'
    },
    root: {
        text: 'Client Folders',
        name: 'Root',
        expanded: true
    }    
});

Attached to the following Tree Panel:

Code:

Ext.define('WebApp.view.admin.pradata.PraFolderGrid',{
    extend: 'Ext.tree.Panel',
    alias: 'widget.prafoldergrid',
    store: 'PraFolderStore',
    rootVisible: true,
    useArrows: true,    
    height: '100%',
    columns:[{
        xtype: 'treecolumn',
        text: 'Client Folders',
        dataIndex: 'foldername',        
        sortable: false,
        flex: 1
    }],    
    forceFit: true
});

The Root node text does not appear in the column:

Any suggestions would be appreciated. Thanks!
