Wah auto engage without touching

[Stratopack]

Hey there, I'm new here. Used my ax8 since a few weeks now. Everything works fine instead of auto engage Wah. Sometimes it turns on without touching everything. No chance to disengage the Wah . Even use of the pedal and then take foot off again does not work. Additional it sometimes turns on while Recording and even if no pedal is connected. You can choose a new preset, it works fine first and after 1 or 2 minutes the Wah turns on automatically. Any ideas?
Thanks in advance

Raise the offset value in the controller tab of the wah a little bit. This shortens the effective pedal way but up to 5% it's not really noticeable
