This was from a thread in January:

>>> The solution is to create a key with the bad label that will overwrite the phantom, then delete it:
>>> 
>>> switch-core1(config)#crypto key generate rsa general-keys label 
>>> switch-core1.ox.co modulus 512 switch-core1(config)#crypto key 
>>> zeroize rsa switch-core1.ox.co
>>> 
>>> and the phantom key will be gone.
>>>
