Why is a group policy on the SYSVOL of one controller but not on the other one?

Hi guys

We have two AD controllers on the same domain and if you access the SYSVOL on one of the controllers, you'll see that there's a policy that is missing. But this policy is sitting on the other controller when you go to its SYSVOL.

All of the other four policies are in both SYSVOL's.

Question is, why is there a missing policy and why are they different to one another?

Thanks for helping
