What am I doing wrong?

We have 2 volumes on the same Netware 6.5 server. Volume 1 is in productin, Volume 2 is archive. When a project is done I personally copy it from volume 1 to 2.

Volume 2 SHOULD have basic read only rights. No modify, no delete, etc. etc. etc.

In consoleOne the Inherited Rights tab shows checks in:
Read, Write, File Scan

In Trustees the "Everyone" group shows just Read, Write and Filescan.
In the "Volume 2 Supervisor group" it shows All checked.

I know I'm the only member of the Volume 2 group.

However, when I check teh "Effective rights" on any given folder for any given user or group it shows they have all rights.

What am I doing wrong?
Thanks in advance for your help!
