Are you trying to set up a second Circle, perhaps at home or another location? If so you'll need to use another device to manage it.
Currently, the Circle app can only manage one Circle device at a time. If you've got two Circles, you'll need to have a version of the Circle Home App on a separate Admin Device (iOS or Android) managing Circle separately from other Circle's. This means that no settings on one Circle will apply to another Circle.
