SuperPINDA (z probe) Always Triggered

SuperPINDA is connected to an Octopus Max EZ as described in the ratrig documentation and the BTT manual (which both agree with each other). Left to right wiring is: Black (switch), Blue (ground), Brown (+5v).

Upon powering switch, I get a glowing red LED from the SuperPINDA. Multimeter readings show a steady +5V between brown (+5V) and blue (ground). Without a piece of metal under the probe, there is zero volts between Black (switch) and blue (ground). Holding a piece of metal under the probe results in the red LED dimming, and 2.3V between the black (switch) and blue (ground) wires.

Regardless of there being a piece of metal or not under the probe, it always reads as "triggered" or closed in Klipper.

Any ideas on what to do? I've attached my probe config as well.
