Discretization for all numeric attribtes by entropy

CheesyWAR

Hi guys! I've been trapped in the step where all numeric attributes in my example-set should be discretized by entropy. I've changed the "balance" attribute's role to the label in order to run the discretize operator but all numeric attributes were discretized in only 1 range in the final result. And if I tick "include the special attribute" the discretize operator would give an alert that the input example set misses a label even though I have changed the role previously. And my problem is" what should I do to make the discretization step work properly?" Apparently, it is not performing well now.
