Just recently found the same thing. Slacken the head off, so it's really spongey, triggers fine. A couple of turns to tighten the repsonse, no triggering at all. I took the head off a and had a look at the piezo wiring, no break, at least none I could see.
The Ddrum Cast precision pads were the best, I wish they'd bring these back! The old Ddrum3 and 4 also has position sensing. The 2box module is by far the best sounding, but I miss pressure and position sensing.
