LZW31-SN unable to set config value to 0 for parameters 9 and 10

Encountering this on parameters 9 and 10 (default level z-wave and local)
I am using openzwave beta. I have been unable to set the value to 0 in both the openzwave addon or when using ozw.set_config_parameter

I have successfully set up an automation to change the value using
node_id: 6
parameter: 9
value: 25

I am able to set the value anywhere from 1-99 both manually and using the automation, but cannot set it back to the default value of 0. Anyone else run into this?
