Autodiscovered Device Security

Hi everyone,

i use Prizm 3.1. And Prizm has create automaticely some Profile called ‘Autodiscovered’ with p.e an SNMP Community public.
But i am sure that on my network dont exist a Device (anymore) with that community.
How can i delete this Profile?

This are the error messages if i try do delete that profile: The Profile is currently used by one or more network elements
