4 way with Homeseer

I wired in as per here:

The first add on Homeseer add on worked fine dimmed up and down, I wired in the second Homeseer add on, now my lights will only dim down, not up… Any ideas?

The homeseer instrucions shows its the load wired through the add ons, the Inovelli directions shows its the Line wired through… Is wiring the Line through right?
