FAQ Tutorial: page created from class sheet is unable to add content

Hi,

I followed the FAQ Tutorial to create FAQ cless, FAQ sheet and FAQ template.

From FAQ class,
I create new page for Title “Q001” and “Q002” pages.
Both pages followed FAQ sheet content to display the class property/value.

However,
when I edit the “Q001” wiki page directly with adding some more wiki content,
the wiki content I added won’t show up.
I was expecting it will show FAQ sheet on the top portion,
and appending the added wiki content at the bottom.

Is tehre any way to do this with class, sheet, template?
