Any idea why I'm getting the giant row that takes up all of page 2? It only
happens when the content following it is greater than a page.

This is expected behavior.
Please read what the book says about splitting tables.
I don't know exactly what you need, but I've made a small
standalone example. If you remove the line setSplitLate(false);
you'll see the example behaves the way you describe.
With setSplitLate(false), you don't get the 'giant row'.
You can also introduce setSplitLate in the master table.
