How to clear a Widget Property?

I’ve mistakenly assigned a slider and a pedal to control the same mapping. I can’t seem to find out from the manual how to clear one of the controllers on my keyboard. What am I missing?

Click on the widget, go to the mapping section on the right and select “no plugin”

So the Clear button isn’t used in this operation?

Are you trying to remove a mapping from a widget to a plugin parameter or a mapping from a controller to a widget?

Initially, I tried to undo the controller mapping to a widget, but couldn’t figure that out, hence my post here.

The Clear button in the MIDI section should do that
