Changing refresh rate is done via nvidia-settings dialog instead of the gnome displays settings one for these drivers, sorry you got caught up in an automated bug bot fight :) The livecd uses nouveau and the gnome settings applet works there, you checked enable third party drivers during the install so it automatically installed nvidia again after.
