Tc electronic stereo chorus flanger low volume problem with mono output

Hello to everyone

I took this pedal a few days ago, but I have a feeling that something is not right
Used in parallel in the effects loop everything seems ok, but if I use it in series, if I connect the mono output (right) the general volume of the sound is lowered considerably, both with effect on and effect off

Voltages on opamps 4558 seem ok, I have a feeling that something in the input buffer of the mono side, is ko

I have to raise the gain trimmer completely clockwise to have a normal (initial) volume

Obviously, on the stereo left channel, raising the trimmer gain I get an Excessive volume

Does anyone have any suggestions?
