I have my pages set up like this:
Item 1 -> Item 2
Item 1 -> Item 3
Item 1 -> Item 4
As you can see, I'm using 'Item 1' as the parent page, sort of as a category for the child items.
The problem is that Item 1 always shows the content of the last child page - right now it shows the items from Item 4 (even though it has no spreadshirt plugin code in Item 1)
