Aux Switch weird communication with Dimmer

I have installed inovelli blue dimmer and aux switch in a 3 way no neutral set up. Everything seems to be working correctly, except the aux switch behavior is a bit odd. The up press and down press register as the same signal, turning the lights on, while the aux “configuration” button registers as the turn off signal. Any suggestions to fix this would be welcome, or if this is the intended design, I’m happy to be corrected!
