Sytrus - Filter Envelop Knobs not working

Hi all,

I'm currently doing the cut-off envelope FL Studio tutorial on Sytrus: https://www.image-line.com/fl-studio-learning/fl-studio-online-manual/html/plugins/Sytrus_tutorial.htm.

I'm currently trying to do step 3.3 of Step 3: Sytrus, the Subtractive Synth, part 2 - a basic filter envelope. When I turn the attack, decay, sustain and release knobs it has no effect on the sound, and when I release the knobs the parameter settings on the display just snap back to what seem to be default settings, I can alter attack, decay, sustain and release by dragging the dots on the display, but I really would like to use the knobs.
