Fx issues in Kontrol S2 MK3

I’m running Mixx on Linux and using my kontrol s2 mk3….everything works perfect apart from the effects. I might be a noob as I’m new no this but I can click on fx but I can’t control the parameters with the superknob. Any ideas on this one?

The knobs in the mixer is mapped to the QuickEffect chains’ superknobs which is separate from the regular effects chains.
