Administration Menus Cover Content

Hello all! Some of the menus in my WordPress Administration site cover the content making it very annoying to use properly. I tried on Firefox 42.0, Internet Explorer 11, and Chrome 47.0.2526.80. This problem has continued through multiple WordPress updates. I am currently on 4.4. You can see a screenshot of the issue here: http://www.PADogRescue.com/wp-content/uploads/2015/12/WordPressIssue.png

Thanks for any help you can provide!
