Shouldn't the chosen Preset be displayed instead of a blank after selecting something from the Pull Down, like chosing Shake...then shouldn't Shake show in the Preset? At least in the Mac version I am running (2018.20) it never shows anything in that Pull Down.
The attached screenshot shows the pulldown as it displays immediately after I have selected Shake - and Shake is actually happening on my Model...so I know it was chosen.
