Aux switch favorite button scene control with Gen 2 Red (LZW31-SN) not activating

Just received an Innovelli 3-way aux switch to replace my old dumb 3-way switch. It’s installed and activates the lights but I’m having trouble getting the favorites button on the aux switch to activate scenes. I’m using Hubitat button controller to select button 7 push which works to activate the scenes on smart dimmer but not the aux. Parameter 21 is set to neutral wired and 22 is set to 3-Wat Momentary. Firmware version is 1.57. Any ideas what could be going on?

I don’t remember for sure (it’s been years since I had a gen 2 switch) but I don’t think they support any scenes from the aux switch.
