SuperPinda triggering too late

I am setting up a new vcore 3.1 and until now I've only used bltouch but this time I decided to go with superpinda 😊. First, I had to reverse the polarity of the probe (removed the '!' otherwise it stayed always triggered...). Then, when homing Z the nozzle rammed into the magnetic bed... It seems that the probe triggers but it happens too close to the bed. I need to set the probe lower than the bed in order to make it work.. Any ideas?
