Pre (Filters/Gain/Phase)

For some reason the Pre (Filters/Gain/Phase) are not working for me in Nuendo 7.1.30 and works just fine in Cubase 9.0.10. I remember for a while I had to hold a modifier to change the gain so I have tried all the modifiers and nothing seems to be working. No modifiers needed for Cubase.
