ZamEQ31 plugin causes distortion on MODEP

Hi all,
Im using latest Patchbox OS with MODEP and PiSound on Raspberry Pi 3B+
When I try to add and connect ZAMEQ31 plugin I get distortion if moving sliders.
I don’t have this problem with other plugins.
Can anyone test this out and see if it happens to you?

can anyone try this out?
