Effect 1 and Effect 2 controls are working just fine for me with ver 3.6.14
Sometimes you can get the controls selected in a way they appear to be reversed. Been there, done that.
Things to check:
Morph box selected
Combined effect dropdown selection
Combined effect slider below the Palette button
You can inadvertently set those to make Effect 1 and 2 appear to be reversed.
For me with ver 14, all is well.
