Bond child devices

I am using the Bond app to control my fans. I have 9 fans and 2 bond hubs. Everything seems to work fine except that the bond child device only shows 5 speeds for my 6 speed fans when working within the rules app. On the child device it shows all 6 speeds but not in the rules app. The lowest speed is called 'very low' and it is missing from the rules app. Am I doing something wrong?

No you are not doing anything wrong. There is an issue with fan speeds.
