TAP Stereo Echo not working

The TOP Stereo Echo is not working in my DUO.

There is a bit of a shift in the sound (small volume change or location of sound off center) Turning the cross knob changes the location of the sound. All other knobs don’t do anything.

I have made sure it’s updated. I also removed it and re-uploaded it but no change.

All other delays seem to be working fine.
Anyone else having an issue with this delay?
