Greetings, divine88!
Depending on your version of the setup file, you may see a blue icon at the bottom left of the setup window that says LUA. If this is the case, you will likely need to toggle it to "REG" first before your settings will take effect. This should be achievable by simply clicking on the LUA icon. Please let us know if that does not help!

Here is a post from GM Fidelis that explains this issue further:
