When i add a second Server i have a Remove Button for both.
This is the same behavior that Manage IPs has. Since an IP must be assigned to a host, there must be at least one host present at all times. To change hosts (or IPs) completely, you just need to add your new one, then remove the one you no longer wish to use.
Also, similar to the IP behavior, the GUI will not let you remove a host if there are currently any IP addresses assigned to it. You must first reassign all IPs to other hosts before it will allow you to remove the host. This prevents orphaned IP addresses.
