I am having some trouble with this feature, as it won't let me adjust the values, it is set on 1/2 and if I click on the arrows to each side of it nothing happens, the value just won't change. I have tried double clicking on it as well, but no luck with that either.

Also, when I save my fx presets and then load them up again, it only saves some of the parameters, not all of them. Has anybody else come across this before?

Thanks for reading.
