Steps to reproduce:
Place a redstone torch next to the calibrated sculk sensor input slot.
Anything that does not send a signal straight to the sensor, such as a lever, pressure plate, or detector rail, will not be input to the sensor.
However, there are exceptions such as redstone blocks.
I could not reproduce the issue. Could you please attach the world to your report, where the issue can be observed? Does your world use any packs/add-ons?
