Missing actuators tab in QGC (px4 1.16)

Hi! I have a px4 scumaker/pilotpi build (v1.16.0) running on the raspberry pi and this setup works well, although there’s no actuators tab in QGC. There’s only motors tab with disturbing message “unable to determine motor count” (screenshot). Does anyone know how to setup px4 so actuators tab is visible?
Downgrading to 1.15 solves this problem, but I want to use new rover_differential module, so 1.15 doesn’t make me happy.
Thanks for any help.

What version QGC are you using?
