Hi @Azizan
This might occur if there is a non-US language used for setting up the GPO. Below are some recommendations that might as well help you in getting proper results from a policy analyzer.
-Add all of the files from GPOs under C:\Windows\SYSVOL\domain\Policies{GPO GUID} on the domain controller. (You could find the group policy name and GUID in the details of GPMC)
- If there are user configurations in one GPO, check if there have a registry.pol file under C:\Windows\SYSVOL\domain\Policies{GPO GUID}\User when adding policy files in Policy Analyzer.
Here is some thread that discusses the same issue and you can try out some troubleshooting steps from this and see if that helps you to sort the Issue.
