OSMC 18.7 Default skin for profiles

Trying to add a profile, a clone of the default, and once set up, I will lock it down for guest access. Using the default osmc skin, the default menu customizations don’t come through when logged on as guest. So (as guest) I go to settings > Interface > Skin > configure Skin > enable menu customisation, which gives the message “In order to customize the home menu a few addons need to be installed first”. Call me crazy, but it would be really helpful to know what addons need to be installed. I don’t get that message when logged on as the default user.
