Hello, Thanks for your response. 

1. Verify the configuration of your tacacs server and ensure it is correctly set up. -> The TACACS servers is working fine for other switches (Cisco NX, Catalyst, SGs) only the Extreme ones are displaying banner twice. So i take is not the Server, unless there is an special requirement for Extreme Switches.
2. Check the login authentication settings on your switch and confirm that tacacs is the primary authentication method.

           This is the settings: aaa authentication login "networkList" tacacs local

3. Review the switch's configuration file for any duplicate or misconfigured banner settings.

No duplicate banners. Just one exists

4. Restart the switch or reload the configuration to see if the issue persists. If the problem continues, you may need to reach out to technical support for further assistance. 

Rebooted it an the same happens. It copies the banner after the first time displayed:
