Closed Unassigned: Bad enum error adding OIDs [46]

Hi

I am trying to add OIDs on a stand-alone offline root CA. I am getting an error about a bad enum:

PS C:\Users\Administrator> register-objectidentifier -friendlyname HighHardAdmin -value 1.2.826.0.1310.30.1.2.13 -oidgroup IssuancePolicy

Are you sure you want to perform this action?
