Can't leave beta El Capitan from app store preferences

I don't have the option of "Your comptuer is set to receive pre-release Software Update seeds". There is only Software Updates are available. I know how to unenroll from apple's developer page but i can't change those settings. Since os x 10.11.1 came out i want to update to that but i can't unenroll from the computer's settings. Does anyone know why? For a while the app store didn't even receive updates until i entered a sudo command into terminal. Thanks.
