Tuya climate Temperature values divider not saved

Hi, I’ve customized the Tuya climate component because my Beca Smart thermostat show doubled values on temperature …
Recent updates seems to add a value to tuya integration that should solve my problem… as documentation says, I’ve set a value of 2 under device option and clicked “submit”, but the value seems not to be saved, if i came back to options… the value “2” Is not there. And the temp values are not divided by 2 as expected.

I’m using home assistant docker version.
