Logging in from the front end disables stickynav to keep menus locked to top of page

Whenever I login to my site from the front end the menus at the top of the page which use stickynav to stay on the top at all times break and the sticynav stops working. I had thought it was caused by the EasyBlog Settings "Render EasyBlog's Own jQuery library" but it ends up not to be the case. Now I believe that something that loads when a person logs in to the front end is disabling the JoomlaBamboo Sticky Navigation.

To reproduce this you can visit the site without logging in from the front end. When you scroll down the page the navigation will become sticky and remain at the top of the page.

Then go to any blog page and using the EasyBlog navigation login to the front end. Now when you scroll down the page the navigation is no longer sticky.

Any idea what is causing this? Does it have to do with the JQuery libraries again?
