Question Why is ApplyParameterOverride() on Action not working?

I am simply trying to change the scroll speed for my mouse input.

Here's my input asset, showing the processor being setup with a default value of 10:


Then here's the code that runs once my GameSetting file is loaded:


And here's the console results, showing that no override has been applied:


Is there anything else that I should do in order to override a processor??

My MouseScrollScale variable is of type float

 

I have tried to apply to both the class (C# file generated) or to the .asset directly, none of them work
