WPG2 with Siriux issue

Wordpress on its own works great, Gallery on its own works great. Even with the plugin its not bad except when I use Siriux theme. I like the very clean look, and on its own in Gallery works well, but when I try and use it inside Wordpress it aligns all to the left, and I can't figure out why!

Any ideas? The example is below:

Thanks for any help or direction you can give!
