I changed the server which had the backup role with a new one.
Before the backup server in my websites was kept as Default.
However I had to use the move website feature to move a website from the old backup server to the new one, before deleting the old server.
Now the new backup server has the "DEDI" flag on it and in the website subscription I'm not able to reset it to "Default".
I even tried using API but it reqires a server UUID and can't be empty.
How can I reset that website subscription to use the "Default" from the backup dropdown and remove the DEDI flag from the backup server role?
