Strange problem, can’t load Brickwall Limiter on Group or Stereo Output channel but works fine on fader channels both mono or stereo.
Using Mac Book Pro and 10.3.
Actually no Dynamics works on Group or Stereo Output. Tried to change a lot of parameters like 64 or 32 bit processing but no difference?
Solved the problem temporarily with an FX channel and Brickwall on that one routing to Output.
