Footer appears in middle of posts pages using BoldGrid

I'm using BoldGrid to set up my site. The footer appears in the correct location on all pages except for individual blog posts. It's ok on the main blog page (showing 10 posts), just out of place on the pages for individual posts. On post pages, it does not float to the bottom of the page, but rather appears in the middle of the page, obscuring the text. For now, I've turned off the footer menu because I did not see a way to fix the issue. Even with the text removed, the darker color of what should be the page bottom design still appears around the first/second paragraph rather than at the bottom of the page. Can anyone be of assistance? Example of what I'm describing: http://bethwaldron.com/a-health-priority-that-is-not-treated-like-one/
Thank you!
