Theme Swift H1 Duplicate

I am not sure if this is a Swift problem, but i have a blog where my front page is a static page, and i have some post, but the issue is that, in the source code there is this H1 tag: <hgroup class=”alignleft”>
<h1 id=”site-title”></h1>
<h2 id=”site-description”></h2>
</hgroup>

I want to remove that H1 tag and i cant find where is it.
Because of this i am having duplicates H1 tags, and i have to hide my Page title because of this.

that code is making my blog title to be a H1 tag and also a anchor text to my site.

And also for my posts if i check the source code the title goes like this: “blog post | Page title”

any thoughts?
