I'm not sure I understand your question...
If you select "Open Only", you can select a page and until you select a voice it won't change no matter what catagory you are in.
If you select "Open and Select", you will have a sound change in each catagory you go to. It remember the last sound used in each catagory.
So, for most people, "open only" is a wiser choice so you can find the sound you want and it waits for you to select it.
