Train Classifer Scope - Extra Parameter

I have been following the DU overview training in UIPath and I am at the stage where I want to retrain my classifier when a document classification has been validated.
I noticed that there is an extra parameter on my Train Classification scope that is not in the UIPath training or in the UIPath documentation .
Can you please specify what "Human Validated Classification Data is used for and where i can get the data to put into it (if I need it).
What is the difference between that field and the "Human Validated Data " field ?


The Human Validated Classification Data argument comes from a Classification Station activity that you can use to validate a classified document. It is mutually exclusive with the Human Validated Data argument that comes from a Validation Station activity.


Thank you , that makes sense now
