Update 2.1.2. NOT WORKING !

My Console:
" | Loaded plugin Entity Limit v2.1.2 by Orange

 | [Entity Limit] Organizing data for plugin, it can take a while, expect small lag

| [Entity Limit] Organizing data: 34000/116245

| [Entity Limit] Organizing data: 37000/116245

| [Entity Limit] Organizing data: 38000/116245

| [Entity Limit] Entity data was organized! "


Can someone please show me how the /config file has to look like so that you can only have 1 test generator?
Tried everything with version 2.1.2


I use the name:
"generator.small": 1
VERSION 2.0.1  is running....
but only the function, nothing else. (messages or other things) Really just limiting the (like me) generator.
