Problems with Proteus 2000 left panel

I’ve cleaned, read, and replaced all I can think of. Even after I run calibration my left panel on my Proteus 2000 is only reading the first half of the pots on the left panel.

I run diagnostics. I go to panel check, turn a knob, and it will go to zero but max out at 127 even though the pot is where 64 should be. It does this on all 5 pots.

If I go to potentiometer diagnostics, it will start at zero and won’t go above 127 unless I move the knob fast. Again it’s got some issue going above halfway unless I move it fast.

Can y’all help me figure out what I’m doing wrong?
