Reset to default value doesn't work in all panels
Exact steps for others to reproduce the error
In render panel, when you right click on "render sampling" and "reset default value", it reset to 64 samples, it is the default value, it is ok!
In other panels, as in node editor, when you right click on "Hue" from "Hue Saturation Value" and "reset default value", it goes to 0, but the default value is 0.5.
