Self Service Portal settings no device limit field

[mhouse]

I am trying to set up the self service portal. I select Enable SSP for this network. When I save changes I get the error "Default Device limit cannot be blank", but there is no option to set a limit

Default device limit is under Trusted Access in Systems Manager > General :

Set this first, and save, then configure your SSP settings / enable
