I've tested everything I can think of... continuity between the Pi and the test pads on the gem, continuity between the button pads and the test pads on the gem, tested all the gnd pads and made sure nothing is bridged, I've cleaned everything with alcohol thinking the pads or the buttons may be dirty... anyone else have a similar issue? All the other buttons work fine, and I've even tried re-configuring the button layout in case something got configured as undefined.
