Unity 300f NAS Multiprotocol - Not seeing updated AD group

I have a share created on my Unity 300f for multiprotocol, I am not using NIS or LDAP, but I can manage the share through Computer Management and add AD groups for access. The issue I have is it doesn't seem to recognize any new groups I created. I have tried Domain Local, Global Security, and Universal, but nothing seems to work. However if I add a group that already existed, it works fine. I can add/remove users without any issues. Is there a way to possibly "re-sync" groups with Unity? I have let it sit over 12 hours, so I don't think it's an issue with domain replication.

Any help would be greatly appreciated, and I can provide additional details if necessary.

Thanks!
