Parent/Child/Grandchild Page HTML displaying incorrectly

I am having an issue with parent and child pages not adding the page HTML in the correct div. I have multiple parent/child levels. Here is an example

Packages
– Clowns
— Clowns In Long Island

For the moment, I am simply using the same HTML for both Clowns and Clowns in Long Island. But when I make Clowns in Long Island a parent of Clowns, using the same template and HTML, the HTML is outside of the correct div.

IE for Clowns, a parent of Packages, using the Package template it’s:

<div id=”contents”>
—<div id=”contents-backpage”>
——<div id=”breadcrumbs”>
——<div id=”sidebar”>
——<div id=”main-content-packages”>
——<div class=”addon”>
—</div>
</div>

But for Clowns In Long Island, a child of Clowns, which is a child of Packages, using the same Packages template it becomes:

<div id=”contents”>
—<div id=”contents-backpage”>
——<div id=”breadcrumbs”>
——<div id=”sidebar”>
—</div>
—<div id=”main-content-packages”>
—<div class=”addon”>
—</div>
</div>

The main-content-packages div and addon div are outside of contents-backpage rather than inside it like the first child.

Does anyone know why a child of a child page does this?
