Mackie Control Pro meters not working (anymore)

I have a Mackie Control Pro (V4) setup with two extenders. The displays used to be able to show channel meters by pressing “Shift+Show Lvl/prm” on the main controller. Now, I noticed that the meters aren’t showing anymore. In the past this used to work. (I am not sure when this issue started). The signal Leds on the channels are working fine though. Anybody (at Steinberg) can confirm this issue?
