Device Handler for GE Dimmer Switches with Settings for All Options

Question for everyone, uncertain if I am experiencing an issue or if it’s working as designed. I have an on/off GE switch that I have the on/off device handler for, I am trying to use this switch to control my basement lights which are a GE dimmer which I also have the device handler for.

My issue is this, I am trying to do a group 3 association where my on/off switch will turn off my basement lights with a double tap. The on/off switch is my stairwell, the master switch is at the bottom of the stairs, the add-on switch as at the top of the stairs. The double tap works when I physically press the master switch, but double tap does not work on the add on switch that is the slave switch to the master switch at the bottom of the stairs.

(also the double tap tiles do not work within the smartthings app when I select the switch)

Bug?

Thanks
