I'm not 100% sure I understand the question correctly, but (if I do) I recall sometimes having to click on the preset window or something, i.e. the correct preset name is in the window, but the actual settings are defaulted 'till I click somewhere. And that's in versions 4,6 and 8.5. Unfortunately the memory is very vague.
Is there some particular setting that is changed/not obeying the preset? Or are all the settings correct (preset name, check boxes) but the result is something different?
