rIdSetReferences missing from DC

Hello tech world, I ran the following command on DC01 (however DC02 passed test RidManager), both are in the same site, both can talk with the Rid Master, all DC's ports are open, i.e 389,636,53,123,88,135,137,138,139,445,464,3268,3269

DCDIAG /Test:ridmanager /v

then got the following error:

Available RID Pool for the Domain is 64878 to 1073741823

FQDN is the RID master

DsBind with RID Master was successful

Warning: attribute rIdSetReferences missing from CN=server,ou=xx,ou=domain controllers,dc=xx,dc=xx,dc=xx

Could not get Rid set Reference :failed with 8481

The search failed to retrieve attributes from the database. Server failed test RidManager
