LD2410 Still Target reporting as Clear even though ≥ 1 gate has energy over threshold

I’m using an LD2410 sensor with ESPHome and pretty much the standard YAML from the docs.

Is there any reason why Still Target would return to Clear (rather than remaining on Detected) even though at least one gate has energy over the set threshold?

Screenshot is from the dashboard I have set up to monitor the LD2410 & ESP32.

You can’t see in the screenshot, but Max Still Distance Gate is set to 6.
