Input Filter (PRE) Dosen't Work

After running Cubase 11, when you create a track and turn on EQ, there is a space on the bottom left that reads “PRE”. Below it is a knob that adjusts LowCut and HighCut, no matter how much you move it, no filter effect appears on the screen, and no real effect is applied to the sound source. I thought it was a bug and tried to reinstall it several times, but the symptoms didn’t improve. I wish I could get a solution to this problem. I Use Cubase 11.0.30.

Hi
You have to turn the filter on by hovering the mouse over the button an pressing it on/off
