Site Title duplicated in SEO page/post title

Hi again. I'm using your Studio theme, which is quite lovely. However, I'm having the same trouble that I had with your Social theme, which is this:

In WP, under Settings - General, my site title is "SoloFirm.net"
In the Studio theme options, my site title is also "SoloFirm.net"

I'm using Yoast's SEO plugin to handle my page/post titles and metas. This is the title template I'm using for pages and posts:

%%title%% %%page%% %%sep%% %%sitename%%

When I go to any page (Activity, for example), the page title displayed in the browser is Activity | SoloFirm.netSoloFirm.net

How do I fix this? Thanks!
