The empty shell presets are only settings. You choose an empty shell preset then go to the Program tab to choose your programs. Then load this program into a generator on the Control Tab.
If you do not choose an empty shell preset but go to the Programs tab first, it will load the default settings which would be the last loaded program in the Control Tab. And if it is your very first time to run anything, it defaults to Healing - Remote - JW.
