Yoast SEO help

[SpaZy.]

Hey,
so i installed yoast to see how it is and it looks pretty good, but i noticed it was duplicating the title
so it would be like

blogpost | | websitenamewebsitename (added the extra '|' aswell)

I changed the title code in header.php to <title><?php wp_title(''); ?></title>

and still nothing, even if i check the force rewrite title option aswell.

I experimented by putting %%title%% - %%sitename%% in the post title template, but it still seems to be duplicating it no matter what.

am i missing something?

You skin has seo enabled .Which is itself producing a title and yoast and producing the second one .
