I have lost all custom formatting in my nav bar

I have suddenly lost all custom formatting in my secondary navigation bar. Yesterday morning it was fine, and somehow through the course of the day all colors switched back to the Prose default settings. I also am unable to change the color of my Global Links. My site is http://www.theodonnellcollective.com.

Can anyone help?
