Unfortunately, we do not work via TeamViewer. Check the console probably your code generated some js error, check you did not miss any close tag while adding your code. If you want to get help from our team with this you need to move WP to live server or contact us later when you move it because we need access to files, WP frontend and backend. We don’t have mentioned issue while added code on our test installation http://prntscr.com/qag864
