When entering values for CMYK in the color selector for precise color selection, it has been remarked that the method is not user-friendly, or values will not save.
Last changed value in dialog does not apply value change unless you click in another value edit field prior to exiting the dialog. ex. C,M or Y values are saved when tabbing to the next field, You must do the same to save the K value. K values will only be saved by clicking in one of the C,M,Y boxes,
