Hello @Verto15,
You have a duplicated record in your queue table. Do you use a 3rd party module for managing the queues?
Do you have access to the server via SSH? If yes, you need to access this database and delete this record from the table.
What is the Asterisk/Freepbx version that you are using?
Thank you,
