RatOS 2.1 Euclid on mellow Fly SHT42 not working

I'm new to the ratOS firmware. I'm current in the process of setting up a new printer with ratos on it. while my other once are being controlled by RRF so I'm a bit new to the entire klipper ecosystem.

I'm currently at the point that my axis move, heaters work and I can home x and y.
however I'm having issues with my euclid probe. I connected everything up.

I'm using the pb1, 5v and grd pins from the sht42 same as shown in the wiring diagram.
I've also verified with a dmm that the signal and ground are connected to one another when the probe is deployed. and when I press the switch the connection gets broken. so all that seems to work as it should.

However if I check the probes in the system tab I see all of them are open. Z/probe as well. no matter if I attach the probe press the switch or detach the probe it always stays open.

anyone have a clue what could be happening?
