Trouble with the scrollbar view

So I have a snippet with the following code. Can’t figure out why the loop elements always decide to put themselves at the bottom half of the window no matter what I have tried so far.

Here is how it looks in game. I want the part in the loop to start from the top but instead there is a big piece of the layout with nothing in it.
window

indent preformatted text by 4 spaces

            m_Window->SetMinWidth(384);
	m_Window->SetMinHeight(500);
	m_Window->SetMaxHeight(700);
	m_Window->SetLayoutSpacing(15);
	m_Window->SetLayout(LM_VERTICAL);
	m_Window->SetAlignment(HA_LEFT, VA_TOP);
	m_Window->SetResizable(true);
	m_Window->SetName("Window");

	// Create Window 'titlebar' container
	UIElement* titleBar = new UIElement(context_);
	titleBar->SetAlignment(HA_CENTER, VA_CENTER);
	titleBar->SetLayoutSpacing(3);
	titleBar->SetLayoutMode(LM_HORIZONTAL);

	// Create the Window title Text
	Text* windowTitle = new Text(context_);
	windowTitle->SetName("WindowTitle");
	windowTitle->SetText(String((m_sType + " " + m_sName).toStdString().c_str()));
	windowTitle->SetFont(cache->GetResource<Font>("Fonts/Anonymous Pro.ttf"), 30);
	windowTitle->SetColor(Color(.3, 0, .3));

	// Create the Window's close button
	Button* buttonClose = new Button(context_);
	buttonClose->SetName("CloseButton");

	// Add the controls to the title bar
	titleBar->AddChild(windowTitle);
	titleBar->AddChild(buttonClose);

	// Add the title bar to the Window
	m_Window->AddChild(titleBar);

	buttonClose->SetStyle("CloseButton");

	ScrollView* scrollArea = new ScrollView(context_);
	scrollArea->SetScrollBarsVisible(false, true);
	scrollArea->SetStyleAuto();
	m_Window->AddChild(scrollArea);

	UIElement* scrollContent = new UIElement(context_);
	scrollContent->SetLayoutMode(LM_VERTICAL);
	scrollContent->SetLayoutSpacing(10);
	scrollContent->SetAlignment(HA_CENTER, VA_TOP);
	scrollContent->SetStyleAuto();

	scrollArea->SetContentElement(scrollContent);

	float sliderValue = 1.0f / (float)m_InfrastructureMap.size();
	auto it = m_InfrastructureMap.begin();
	while (it != m_InfrastructureMap.end()) {
		UIElement* currentI = new UIElement(context_);
		currentI->SetLayoutMode(LM_HORIZONTAL);
		currentI->SetLayoutSpacing(10);
                    currentI->SetAlignment(HA_CENTER, VA_CENTER);
		scrollContent->AddChild(currentI);
                    .................
                    currentI->AddChild(text);
                    it++
            }
indent preformatted text by 4 spaces

Finally saw that child added to the window previously had grown to a weirdly large size so it was placing the next element way down in the window. Just had to set a max height on the child ui elements.

Expect headaches when you first start using ComboBox UI elements. They’re the trickest UI element to use (though I believe Weitjong added warning messages a year or more ago since people kept getting tripped up by combo-boxes).
