User view article write with Registered user

[shuttle78]

Hi,
for a particular user, I've created a new user group and access level configured for show only 1 item on menu. The problem is that the articles are written with Registered group.
How to read this article?

On category manager I've put another user group, configured with Registerd Users e my user but doesn't work.

Example:

User TI -> User group TIAccessLimit -> Access Level with TIAccessLimit checked
User Group TIAccessLimitRegistered -> Access Level with "TIAccessLimit" and "Registered" checked

On category manager I've selected TiAccessLimitRegistered.

How to resolve the problem?

Thanks a lot
Regards
