The limits hook library uses the name to identify a client class and the ID to identify a subnet.
Changing a test expression in a client class or the network range of a subnet while leaving the
name, or the ID respectively, unchanged will not reset the limit for the respective client class
or subnet and what counted towards the limit prior to the change, will continue to take effect.
To start over, consider changing the client class name or the subnet ID.
