Are you stepping on the pedal multiple times after each other?
As i wrote in my first reply, then Piano sounds can be coded to produce pedal sounds just like a real piano has. You wrote it's on all presets, but all the presets you mention is Piano sounds, so it's not strange.
Do you have the full Piano V2 application? In that case you can remove the sound, as it's a parameter in Piano V2, if it come from that. The sound you have recorded sound like it is. That's also why you can record the sound.
