Optimization Grid with Random Forest - Not Working.

RapidMiner Unicorns 🦄,

I trying to run a optimization grid with our my Random Forest model and I am getting an error.  It's stating that gain_ratio criterion cannot be used for numeric labels (see pictures below).  I checked all my parameters and I am not using gain_ratio in the optimization grid (see pictures below).  So, specifically how you used a optimization grid with cross validation, and random forest predicting a real number in RapidMiner? 

Can you send an basic working example of this workflow process with with good documented comments explaining each step.
