I'm using ArcMap 10.5.

With the "Image Classification" tool I create all the polygons with the training areas for each class. I use "merge" and give the name of the classes (ocean, river, urban...) and when I have all the training areas I click on "Interactive Supervised Classification" and heres come the problem, it only represents the color of the class that have the lowest number in the value field on the table of the "Training Sample Manager" window. I checked this changing the number on the value field for a class and putting the lowest value there and when I clicked again "Interactive Supervised classification" it shows me the color of this class.

Did you know what's going on and what can I do to see also the colors of the rest of the classes?
