Train Classifier Scope wrongly detect both parameters?

Hi all. New to UIPath here. I have some issues while trying to create an automated invoice detector.

  1. It detects the value of classifier as null but I have actually ticked the field within “configure classifier”
  2. I provided exactly one field under “Human Validated Data” and left out “Human Validated Classification Data” in which the system wants me to only provide a field (which I did)

How can I fix this issue? It’s been bugging me for hours but I cannot find any solution to it.

Some other information:
I followed the exact step of UiPath Academy
