When I click "Sub Menu Align Right" nothing changes

Hello,

I love your plugin. Working great except for one thing. When I click “Sub Menu Align Right” in the menu area nothing happens. The sub menu is always aligned to the left side of the page.

Here is the link to the test page:

test.thechromecrew.com

The offending sub menu is under the “Archive Gallery” tab.

Thanks much.
