Saving Presets

Can anyone explain why i cannot save any presets? If i insert a plugin in a audio channel as usual & make my own settings i then wish to save this as a presets for future use. I click either in the menu or the little box & choose the save. I type in a name & nothing happens. It is not saved or added to the list (which is usually blank as no others are saved either).
Is this just something happening to me?

I am having the same problem, I have saved plugin settings and when I search for them they are missing. Cant find them. But i search for other plugins and they are available.
