High End Theme: formatting wonky on portfolio page

Hi there,

I’ve got a quick question about a formatting issue that seems to have cropped up on my portfolio page. I have separate tabs set up for each of my clients, and now the tabs seem to spill out across the horizon on the right-hand side of the browser. I’m using Firefox to view the portfolio page right now, but the same thing happens in Chrome. Here is the link:

Thank you!
