Page Headlines

[SoHo22]

Hi,
the site I´m developing has a structure as follows:

Home (index.php)
subpage 1
subpage 2 ...
Next Mainpage
subpage 1
subpage 2 ...

Page headlines are called by <?php get_page_title(); ?>

And they are correctly shown on Next Mainpage > subpage 1 ...
but on Home > subpage 1 ... there is still the Headline of Home.

I use the multileve I18-navigation, which works fine. Deactivating it has no effect on this headline problem.

Has anyone an idea?

Thanx
SoHo
