Adding a frontpage slideshow to gridmarket.

Hi Support,
I am using the framemarket/ grid market template, but would like to add a slideshow to the frontpage.
I have created a page and set that to frontpage, but I cant seem to find out which template file I can remove the page title in.

I have tried to remove the <h1 class="post-title"><?php _e( 'Our products', 'framemarket' ) ?></h1> in the index.php file, but it doesnt work.

Where can I change this?
