Unsupervised Classification runs on wrong number of classes?

So my problem is that I am running an unsupervised classification, and for some reason it is not running on the correct number of classes. If I try to run a 12 class classification, it returns only 10 classes. I have no idea why this is happening, as it runs correctly for a different set of data.

#Unsupervised Classification
    Classified= Divided
    Output_signature_file= "Scrap.gsg"
    outUnsupervised = IsoClusterUnsupervisedClassification(Filtered, 12, 20, 10, Output_signature_file)
    arcpy.AddMessage("Unsupervised classification complete.")
