Line6 MM4 mod gone bad?

[punxtian]

Hi everyone! I'm new in this forum so please be patient. I just want to ask a few questions i hope you can help me. I tried modding my Line6 MM4 to fix the vollume drop last night. I was able to put the resistor at R37 but i messed up R36. I tested the pedal and the volume drop is fix but when i try to disengage preset no.3 i hear this clicking sound. Do you know what's causing the clicking sound? Is it because R36 is gone? Thank you in advance!
