There are duplicate working copies of the policy you are trying to edit saved in Group Policy Management Console (GPMC) and in the local temp directory.

·         Remove all the working copies of the policy from within GPMC > Group policy objects

·        Remove the temp files from C:\users\GPOAdmin service account\AppData\Local\Temp\Avalanche

·         Restart the GPOADmin service
