I'm trying to create a filled contour feature class from a GA layer using the manual classification type option but when I do this, ArcMap will not allow me to set the number of class or change any of the class breaks.

To remove a class, select the row and click the delete icon (X). You can also select multiple rows to delete.

To add a class, type it into the Class breaks control and hit the add icon
