"Right could not be revoked" from everyone

We are running RT 3.4.3. So far the only real problem is related to rights, in the sense that everybody is seeing everything.

Reviewing the assignments to the “everyone” Group I found that it is assigned the “DelegateRights” and “SuperUser Right”. When I try to remove these rights I get the message: “Right could not be revoked”.

I’d appreciate any advice on how to fix this issue.

Thanks in advance for your help,
