Cubase faders not feeding back

Hi, in Cubase if I move a fader the fader in OSC does not move, if I use a dial for example EQ filter does respond, I hope that makes sense?

Also I’m wondering if you can have it button to change the workspace instead of swiping, as I have six workspaces I then have to swipe several times which for me is counter-productive, as I have dyspraxia it gets tiring and be more visual and quicker to have a button to change the workspace, any help or advice would be welcome.
