In case your simulation is executed using ModelSim, when you invoke any kind of simulation within the ISE environment, ModelSim is automatically opened. By default one of the window that comes up is the Wave View window. In this window only the top entity signals are shown, and ... no any other signal ... So if you want to see internal signals of your design, or maybe you want to change the position and/or color of a signal, maybe you want to add dividers,or utilize many other features offered by ModelSim, you can do that in the window that is automatically opened, but. . . any change in the Wave View window will be kept until ModelSim is closed. When running the same simulation again, you should start with the changes that you want once again from scratch.
I've written a kind of application note that describes the necessary steps to follow, so when you invoke ModelSim from ISE, the Wave View will open (keep) any change you have done to the initial (default) window, containing all the information you want/need for proper verification and easy debug:

Happy design!
