Page History

Using the following:

{pagetree2:@home|showRoot=false|branchStyle=arrow|showIcons=false}

and expecting (as viewed from another page):

Page1
> Page2
Page3
...

Page2 has a child, so if you click on the arrow, you should get:

Page1
v Page2
Page2a
Page3
...

But all I get is:

Page1
Page2
Page3
...

Now if I go to Page2 I see:

Page1
Page2
Page2a
Page3
...

The arrow is completely missing.

How can I get this to work correctly?

Thanks,
