[SOLVED] Changing position of blog title

I like to use the Atahualpa theme (it's really great), but I can't get my finger on the next thing:

at http://overlegbk.nl/wordpress/ you can see the blog title 'Overleg Beeldende Kunsten'

All pages look equal according to the position of the blog title (homepage, http://overlegbk.nl/wordpress/?page_id=2 and http://overlegbk.nl/wordpress/?page_id=7), but the page I am using for showing my blogposts (http://overlegbk.nl/wordpress/?page_id=12) looks different.

There the blogtitle (and the page as a whole) jumps up.

my Atahualpa configuration:
- Style & configure LAYOUT>Layout Container Style>margin-top: 40px;
- Style & edit HEADER AREA>Blog Title>margin-bottom: 10px;

Can somebody help me out?

Many thanks in advance
