Strange Admin Issue

Just recently, and after NO changes, my blog started looking messed up when I was in the admin area. What I mean is that while I’m logged into the admin area and look at the site, some of the admin links show with a broken template beneath the theme.

Does anyone know what might be causing this? You can see a screenshot at https://lee-wilson.net/wp-content/uploads/2015/04/screen-shot-of-error.gif

Thanks for any suggestions/help!
