Threshold Sensor Helper Configuration Issue?

I have been playing around with a threshold sensor helper, and have been getting an unexpected result. I am using it to tell me when a room’s temperature becomes outside of comfortable limits. The goal is for the sensor to be OFF when the temperature is between 55 - 80 F, and ON when outside of that range. The following screenshot shows my current configuration, based on the documentation and from a post by a moderator in these forms named tom_l:

As you can see, the sensor value is between the limits defined by the upper, lower, and hysteresis. Regardless, the “Position” is reported as “unknown” instead of “Off” like I would expect. When the temperature does move out of this range, it switches to “On”, but then goes back to “Unknown”.

Anybody else have this result with the Threshold helper? Am I just configuring this straight up wrong for my use case?

BTW this is on Home Assistant Core (Docker Container) 2022.9.5 running on a RPi 3B+
