Rally kanban cards show parent for features - rally

Question

I have no issues showing the parent for features in my cardboard when the cardboard is only displaying features:
cardConfig: {
xtype: 'rallycard',
listeners: {
fieldclick : function(field, card) {
_loadDetails(card);
}
},
fields: [
'Name',
// 'Parent' - either one of these ways works
{
name: 'Parent',
fetch: ['Parent'],
renderTpl: Ext.create('Ext.XTemplate', 'Parent: {Parent.Name}')
}
]
},
However, when my kanban board is displaying both features and rollups, the parent information does not display on the card. I have tried conditionally setting it, or using a renderer instead of a renderTpl (the renderer was never called) - I cannot find a way to do this correctly in the API docs.

Here is an App.js code where the Theme cards do not show Parent field, but Feature and Initiative cards do:
Ext.define('CustomApp', { extend: 'Rally.app.App', componentCls: 'app',
launch: function() {
var addNewConfig = {
xtype: 'rallyaddnew',
recordTypes: ['PortfolioItem/Feature', 'PortfolioItem/Initiative', 'PortfolioItem/Theme'],
ignoredRequiredFields: ['Name', 'Project'],
showAddWithDetails: false,
};
this.addNew = this.add(addNewConfig);
var myCardConfig = {
xtype: 'rallycard',
fields: ['State','Parent']
}
var cardBoardConfig = {
xtype: 'rallycardboard',
types: ['PortfolioItem/Feature', 'PortfolioItem/Initiative', 'PortfolioItem/Theme'],
attribute: 'InvestmentCategory',
cardConfig: myCardConfig
};
this.cardBoard = this.add(cardBoardConfig);
}
});
