Vimeo Full-Screen Issue?

I just noticed that when you try to go full-screen on Vimeo videos that are embeded on my site that it opens off to the side of the site.

Here’s a link with a Vimeo video embeded on my site. If you hit that full-screen mode it should do it for you.

I’ve seen this happen on one other site and now I’m trying to decide if it’s a coding issue on my end, or a Vimeo thing? Youtube videos go to full-screen with no issues.

Any ideas?

Thank you!
