When wanting to change the settings for a specific calendar the path to do this is different for the iphone and laptop.
Steps:
Computer: Double click on calendar.
Phone: Scroll all the way down and click on the gearwheel and then 'edit'.
Expected: Same path, for example double clicking on the calendar on the iphone should also take one to the settings.
