Random Forest validation

Hello everyone! I am trying to validate a Random Forest model through the Validation option. However, for every options I select in the 'validation set', the following error comes: "A category is present in the validation data, while it is not present in the active data..." How can I solve this? 

Thanks

    Is it possible for you to post a copy of the workbook on OneDrive or GoogleDrive with a link here that grants access to it. That way even those of us who haven't ever heard of the Random Forest Model might be able to respond.

     

    For those who don't have the slightest idea what a Random Forest Model is (I'm among that group), here's a link to Wikipedia.
